Abstract

STRUCTURAL AND MORPHOLOGICAL CHARACTERISTICS OF PLASMA SPRAYED TiO2-COATINGS. TiO2 thin layers have been deposited on glass substrates using Plasma Spray technique. The TiO2 starting powders are a laboratory grade commercial powders. Before spraying, to check the availability of the basic material for Plasma Spray technique, a series of characterization was conducted. The TiO2 starting powders were identified its particle size using Particle Size Analyzer (PSA) resulting diameter at 90% was 42.72 µm. X-Ray Diffractometer (XRD) measurement was done to identify the peaks of the basic material elements using Kα radiation at wavelength 1.5406 Å resulted TiO2 of Anatase structure. Spray dry process was then conducted in order to get circular and free flowing particles for feedstock of plasma spray system. Distribution of particles showed a dominat of 20 µm diameter-free flowing particle. Plasma Spray process of TiO2 powder furthermore was conducted on slide glass microscope under several parameter conditions such as power, flame-substrate distance and preheating treatment variation. The TiO2/glass coatings with variation of flame-substrate distance (10 and 12 cm) resulted in 5.806 µm and 4.913 µm layer thickness with grain size in the range of 0.8-2 mand 1-2.8 µm, respectively. XRD diffractogram results revealed that the TiO2 layer are dominat in rutile phase but at a little higher of plasma power, low anatase phase existed. The preheated-plasma sprayed TiO2 coatings were visibly difussed into the glass substrate and resulted in dominat rutile phase (at 2 cycles preheating) but not existed in a longer preheating time (4 cycles preheating treatment).

Abstract

PREPARASI DAN KARAKTERISASI HIDROKSIAPATIT BERPORI DARI TULANG IKAN. Telah dilakukan pembuatan hidroksiapatit (HAp) berpori dengan bahan dasar limbah tulang ikan dan sebagai bahan porogen kitosan dengan metode kalsinasi pada suhu 1.100 °C selama 5 jam. Analisis termogravimetri dilakukan dengan Simultan Thermal Analyzer (STA), identifikasi fasa dilakukan dengan X-Ray Diffractometer (XRD), analisis strukturmikro dengan Scanning Electron Microscope (SEM). Analisis termogravimetri menunjukkan puncak penurunan berat pada suhu 365,6 °C dan setelah suhu 500 °C tidak terjadi penurunan berat lagi. Identifikasi fasa menunjukkan adanya fasa hidroksiapatit pada tulang ikan mentah dan tulang ikan setelah dikalsinasi pada 1.100 °C selama 5 jam. Hasil SEM menunjukkan strukturmikro berpori antar partikel pada tulang ikan mentah dan setelah kalsinasi 1.100 °C selama 5 jam dengan ukuran partikel sebesar 0,1 μm hingga 1,0 μm. Setelah penambahan kitosan, pori antar partikel yang terbentuk lebih merata dan jelas.

Abstract

DETERMINATION OF DIELECTRIC PROPERTY AND IONIC CONDUCTIVITY OF CdS/SO3H-P(S-DVB)] nano composites with different CdS contents were successfully synthesized by ion exchange and precipitation processes at SO3H-P(S-DVB) matrix. The characterized, dielectric property and ionic conductivity of the nano composites were also examined. The polymermatrix and the chemical interaction between CdS nano particleswith polymer were analyzed using Fourier Transform Infrared (FT-IR) spectroscopy. The CdS nano particles was confirmed from Diffuse Reflectance Ultraviolet - Visible (DR UV-Vis), X-Ray Diffractometer (XRD) and Atomic Absorption Spectroscopy (AAS) analysis results. Scanning Electron Microscope (SEM) techniques were used to observe the particle size of the nano composites,while amorphology of the nano composites was also investigated using Transmission Electron Microscope (TEM) techniques. The SEM and TEM studies showed that the CdS nano particles are attached on the surface of polymer matrix. Dielectric property and ionic conductivity of the nano composites have been studied using an Impedance Analyzer, respectively. Present study shows that the influence of CdS nano particles loading levels on the dielectric property and ionic conductivity of the nano composites. The dielectric constant and ionic conductivity of the CdS/SO3H-P(S-DVB) nano composites decreased with increasing content of CdS nano particles as effect replacing of proton by CdS nano particles, respectively.

Abstract

PENGARUH KONSTANTA DIELEKTRIK DAN DISPERSITAS PARTIKEL TERHADAP HYDROPHOBICITY ELEKTROKATALIS BERBASIS CARBON NANOTUBE. Pada penelitian ini dilakukan pembuatan lapisan elektrokatalis berbasis Carbon Nanotube (CNT) dengan teknik filtrasi untuk meningkatkan sifat hydrophobicity. Sifat hydrophobicity elektrokatalis diperlukan untuk mengurangi penggunaan hydrophobic agent, yaitu PolyTetra Fluoro Ethylene (PTFE) yang ditambahkan pada elektrokatalis komersial Pt/C untuk mengatasi air yang dihasilkan di elektroda. Pembuatan lapisan elektrokatalis dilakukan dengan metode filtrasi dari elektrokatalis terdispersi menggunakan membran hidrofilik. Beberapa teknik pembuatan dan formulasi larutan dilakukan untuk meningkatkan hydrophobicity tanpa mengurangi performanya. Pada kondisi larutan padat antara pelarut yangmempunyai konstanta dielektrik (ε) >10 dengan ionomer nafion akan menghasilkan hydrophobicity yang tinggi (>90°). Sedangkan pada kondisi colloidal state antara pelarut dengan konstanta dielektrik (ε) <10 dan ionomer nafion cenderung tidak mengubah sifat hydrophobicity (<90°). Sifat hydrophobicity elektrokatalis diukur dengan teknik Half Angle menggunakan Contac Angle Meter. Perubahan morfologi permukaan lapisan elektrokatalis akibat penambahan nafion dan dispersi partikel CNT diamati dengan Scanning Electron Microscope. Hubungan antara penambahan larutan nafion dan hydrophobicity film dibahas pada makalah ini.
