Evaluation character of chitosan membrane-succinate / poly vinyl alcohol-poly ethylene glycol (PVA-PEG) were prepared in acetic acid solvent through a phase inversion method has been performed. The study began with the preparation of crosslinked chitosan compounds with succinic acid, followed by preparation into membrane by combining PVA-PEG. Character analysis of the resulting material using FTIR, EDX, TGA, water absorption test, tensile strength, membrane hydrophilicity. The ability of membrane permeation was tested against creatinine. The results showed that the succinate had reacted with chitosan. Chitosan modification through cross link and polymer alloys increases tensile strength and membrane strain of 1.7-2.5 x of pure chitosan membrane. In addition, the modified membrane also has higher water absorption and hydrophilicity values than the unmodified membrane, and this implies the ability of membrane-induced creatinine permeation. Permeable permeation values were 13.8% in chitosan, 24.84% on chitosan-succinate and 25% in chitosan-succinate / PVA-PEG. Chitosan-succinate membranes have the ability to use more than 4x repeated use.

This study investigated the effects of additional PVA on the physicochemical properties of the chitosan-glutaraldehyde/gelatin bioplastic composite. The best results of the bioplastic film were obtained at a concentration of 3% PVA, with a tensile strength value of 3.3 MPa, flexibility reached 54%, a thickness value of 0.24 mm, percentage of inhibition against E. coli and S. aureus was 21.8% and 8.8% respectively. The FTIR spectrum results showed no change in the wavenumber of the chitosan and gelatin chitosan spectrum with OH, CO, and NH functional groups. The spectrum indicates that only physical interactions occurred. The bioplastics are similar in thermal stability and have slight differences in bioplastic morphological contours. The average thickness of the bioplastics is between 0.20–0.26 mm. Based on the Japanese Industrial Standard (JIS), all bioplastics meet the standard thickness, which is < 0.25 mm, excluding chitosan, which has a thickness of 0.26 mm. The addition of PVA into the bioplastics structure increased the hydrophobicity, pH resistance, and flexibility of bioplastics. Meanwhile, additional PVA decreased biodegradability, only degraded by 60% at eight weeks. Based on these data, not all bioplastics can meet the degradation time criteria set by the international bioplastic standard ASTM D-6002, that bioplastics must be 100% degraded within eight weeks. Bioplastics made from chitosan and chitosan-gelatin have been degraded by 90% for 48 weeks. Based on the antibacterial properties, the inclusion of PVA into the bioplastic structure enhances the antibacterial properties.

The investigation of membrane-based hemodialysis is an interesting study due to its efficacy in eliminating metabolic waste compounds, such as creatinine, from the body. However, not all membrane types exhibit optimal transport capabilities, necessitating modifications. In this study, we conducted modifications on chitosan (CS) membranes by incorporating polyvinyl pyrrolidone K-30 (PVP K-30) and assessing their physicochemical characteristics. The modified membrane underwent characterization and subsequent evaluation of its transport capabilities. The primary objective of this research is to design a membrane composed of chitosan and PVP K-30 with enhanced creatinine transport capabilities. The study commenced with the fabrication of CS membranes combined with CS-PVP, involving six variations of CS and PVP K-30 with volume ratios of 5:0, 4:1, 3:2, 1:1, 2:3, and 4:1. The resulting solution was then printed into a flat sheet membrane. All completed membranes underwent comprehensive characterization, including tests for functional groups using Fourier Transform Infrared (FTIR), membrane weight and thickness, porosity, water absorption, swelling, hydrophilicity, pH resistance, and biodegradation. In the final phase, the membrane was utilized in the creatinine transport process. FTIR analysis of the CS-PVP K-30 membrane revealed O-H and N-H group spectra at wave numbers 3363.06 cm-1 and 1587.17 cm-1, indicating hydrogen bonding between the two polymers. Characterization tests demonstrated that the CS-PVP membrane exhibited increased porosity, water absorption, swelling, and hydrophilicity. In the creatinine transport test, the CS-PVP membrane demonstrated enhanced creatinine transport ability compared to the CS membrane. The highest clearance value for creatinine was observed in the CS-PVP5 membrane, with an increase in the amount of PVP K-30 correlating with an elevated creatinine clearance value. The creatinine clearance values for the CS membrane, CS-PVP1, CS-PVP2, CS-PVP3, CS-PVP4, and CS-PVP5 were 0.30, 0.36, 0.37, 0.39, 0.42, and 0.46 mg/dL, respectively.

High concentrations of creatinine and urea in the blood can be removed by dialysis using semipermeable membranes that are selective for certain species and hold other species through diffusion processes. This ability requires a membrane that has an active side, which functions as a targeted species identifier. The membrane must be biocompatible because the membrane will be in direct contact with the body’s biological systems. The membrane material that is made must be acceptable to the blood system so that there is no rejection from the body and have a large contact area to obtain an effective diffusion process. For this reason, a hollow fiber membrane (HFM) is needed. One of the synthetic polymers used as the base material for HFM is PSf. PSf has mechanical strength, heat resistance, and is easily formed into HFM. However, PSf has disadvantages such as lack of active side and less compatible with blood due to its hydrophobic properties. Modification using PEG and chitosan will reduce the hydrophobicity of the PSf. Membrane results were analyzed the physical, chemical, and transportability for urea and creatinine. The results of functional group characterization by FTIR show that the modification reaction was successfully carried out on polysulfone to produce PEG-PSf/CS. The modification succeeded in making the PSf membrane more hydrophilic, as evidenced by a decrease in the contact angle from 69.4° (PSf) to 53° (PEG-PSf/CS). Water uptake capability increases to 609%, and membrane porosity increases porosity increased from 72 to 83%. The water flux is also increased. Creatinine clearance ability increases from 0.09 mg/dl to 0.25 mg/dL. Urea clearance ability increases from 2.3 mg/dL to 3.07 mg/dL. The SEM image showed that the modification makes the membranes more porous.

Penelitian tentang modifikasi kitosan menggunakan taut silang natrium tripolifosfat (NaTPP) dengan paduan polivinil alkohol (PVA) telah dilakukan. Tujuan penelitian ini adalah memperoleh membran kitosan tertaut silang TPP dengan paduan PVA dan mengkarakterisasinya kemudian mengaplikasikannya untuk uji permeasi terhadap kreatinin. Penelitian ini dilakukan dalam beberapa tahap yaitu sintesis membran kitosan termodifikasi NaTPP dan PVA, karakterisasi membran dan aplikasi membran untuk permeasi kreatinin. Penelitian diawali dengan membuat larutan kitosan (Cs), kitosan-PVA (CsP) dan kitosan termodifikasi NaTPP dengan variasi mol kitosan:NaTPP yaitu CsPT1 (1:30), CsPT2 (1:20) dan CsPT3 (1:10), kemudian mencetaknya menjadi membran. Tahap berikutnya, mengkarakterisasi membran meliputi uji FTIR untuk mengidentifikasi gugus fungsi, uji morfologi permukaan menggunakan SEM, uji serap air, daya pengembangan, porositas, hidrofilisitas, kuat tarik dan uji permeasi terhadap kreatinin. Keberhasilan sintesis membran kitosan tertaut silang NaTPP dengan paduan PVA dibuktikan dengan adanya pergeseran bilangan gelombang dari 3280 ke 3251 cm-1 yang menunjukkan adanya interaksi antara gugus O-H dan -NH2 dari kitosan, PO- dari TPP dan -OH dari PVA. Hasil karakterisasi fisik membran termodifikasi pada pengukuran berat dan ketebalan membran, uji serapan air, porositas dan hidrofilisitas meningkat seiring peningkatan kadar NaTPP, sedangkan pada uji kuat tarik dan pengembangan mengalami penurunan. Membran terbaik pada permeasi kreatinin adalah membran CsPT3 dengan kenaikan persentase transpor kreatinin sebesar 33,17% dari membran kitosan awal.

A slow-release test of urea fertilizer was conducted using chitosan-urea (CS-U) and chitosan/polyvinyl pyrrolidone K30-urea (CS/PVP-U) membranes. The urea membrane synthesis involved a blending method, with PVP K30 added as a component. The slow-release capabilities of CS-U, CS/PVP1-U, CS/PVP2-U, CS/PVP3-U, and CS/PVP4-U membranes were compared. FTIR results showed an increased intensity of the primary NH double peak at 1587 cm-1 and 1640 cm-1, while the C=O spectrum shifted from 1640 to 1647 cm-1 and the -OH group from 3354 cm-1 to 3362 cm-1, indicating hydrogen bond formation in CS/PVP-U. XRD analysis confirmed the membrane’s amorphous structure, and FE-SEM and AFM studies revealed morphology and roughness differences, with CS/PVP4-U having the largest cross-sectional diameter. The release study showed that PVP-modified chitosan membranes increased urea release, achieving 60 ppm/2 days for the first 16 days, then decreasing to about 55 ppm through day 30, with partial urea release controlled over time. This suggests that SRF fertilizer can effectively control urea release into the environment.

This research aims to synthesize and characterize a bacterial cellulose (BC)-based composite with graphite and TiO2-ZnO as reinforcement materials using ex-situ synthesis with CTAB as a surfactant. FTIR and SEM-EDS analysis revealed interactions between the matrix and the reinforcement materials, as well as irregular particle distribution in the BC/G-TiO2-ZnO composite. The addition of graphite to BC significantly increased the conductivity of the composite, while the addition of TiO2-ZnO had the opposite effect. The mechanical properties of the composite exhibited an inverse relationship with the conductivity parameter. Swelling tests indicated that pH and the addition of CTAB influenced the swelling behavior of the BC-based composite. The results of this study provide a strong foundation for the development of potential applications in the fields of electronics and pollutant filtration. The synthesis of this composite aims to harness the unique properties of BC, graphite, and TiO2-ZnO, creating a multifunctional material with potential uses in flexible electronics, sensors, biocompatible conductive materials, and advanced filtration systems.

A chitosan-zinc oxide (ZnO)/poly(ethylene glycol) (PEG)/pomegranate peel extract (PE) based hydrogel has been developed as a potential material to accelerate the wound healing process by controlling the drug release mechanism. ZnO nanoparticles with an average size of about 95 nm were synthesized using the coprecipitation method and then combined into chitosan/PEG composites to improve the antimicrobial properties of the hydrogels. Characterization of the hydrogels included analysis of size, morphology, elemental composition, microstructure, swelling behavior, antibacterial activity, and wound healing effectiveness. The results of the in vitro study indicated that the antibacterial activity of PE-containing hydrogel against Escherichia coli and Staphylococcus aureus decreased due to the chelation effect caused by PE addition. However, in vivo tests for 10 d showed that the PE-containing hydrogel had better wound healing ability than commercial betadine. In addition, the developed hydrogel showed high biocompatibility with excellent antibacterial activity. This study confirmed that chitosan/PEG/ZnO nanoparticle hydrogel has the potential as wound dressing materials with sustained drug release and optimal healing effectiveness.
