Polysulfones are hydrophobic which can reduce membrane permeability. Permeability can be increased through the application of hydrophilic materials such as GO-Fe3O4 to the polysulfone membrane so that the membrane is hydrophilic. The riset purpose to determine the effect of the percentage weight of different material compositions on the hydrophilicity properties of the polysulfone membrane. Membrane fabrication is carried out using the phase inversion method where the polymer solution is molded in a place and immersed in a coagulation bath containing non-solvent. This solvent exchange causes the polymer to form a solid matrix and become a membrane. The results showed that GO particles were successfully doped with Fe3O4 material shown by XRD analysis at a peak of 35.61˚ with a magnetite phase, while FTIR analysis showed that there was an absorption band characteristic of Fe-O streching vibrations. The results of the contact angle test on the GO-Fe3O4/PSF membrane 0.75 wt per cent were around 73.17˚ which showed the smallest hydrophobic value and the membrane surface morphology had an average pore size of 333.61 nm so that the addition of GO-Fe3O4 composites could increase membrane hydrophilicity.DOI: 10.17977/um024v6i22021p055

Polyaniline (PANi) was succesfully prepared from Ammonium Peroxodisulfate (APS) and anyline using chemical oxidation method. Silica (SiO2) was synthesized from natural sands taken from Banjar. PANi/SiO2 composites were prepared using mechanical mixing route. The composites were prepared by variating the weight compositions of PANi:SiO2 of 2.5%, and 5% for SiO2. Furthermore, the coating process of Paint-PANi/SiO2 on SS304 stainless stell by spray coating technique. The characterization of anticorrosive behaviour of Paint-PANi/SiO2 was tested by potentiodynamics method. The obtained Tafel curve was then analyzed by means of ANOVA method. The best anticorrosive performance refered to the sample of Paint-PANi/(5%)SiO2, both of before and after exposure processes. The corrotion rate of before and after exposure processes were 0,00896000 mpy and 0,00024408, respectively. DOI: http://dx.doi.org/10.17977/um024v1i12016p025

Abstrak Sintesis nanokomposit Fe3O4@SiO2 telah dilakukan melalui dua tahapan. Pertama, sintesis nanopartikel Fe3O4 dan SiO2 dari bahan alam pasir besi Lumajang dan pasir bancar Tuban mengggunakan metode kopresipitasi. Kedua, sintesis nanokomposit Fe3O4@SiO2 dengan cara mencairkan PEG 4000, kemudian ditambahkan Fe3O4 dan SiO2. Hasil sintesis nanokomposit tersebut dikarakterisasi menggunakan XRD, FTIR, Suseptibilitas magnetik dan TEM. Hasil karakterisasi XRD menunjukkan bahwa struktur fasa dari nanokomposit Fe3O4@SiO2 berhasil terbentuk. Hal tersebut didukung oleh data hasil FTIR berupa pola serapan gelombang yang teridentifikasi memiliki ikatan Fe-O-Fe dan ikatan Si-O-Si yang menyatakan bahwa modifikasi permukaan Fe3O4 telah berhasil dilakukan dengan menggunakan SiO2. Selain itu, hasil karakterisasi suseptibilitas magnetik menunjukkan bahwa nilai suseptibilitas magnetik menurun dengan penambahan silika dan sampel termasuk dalam jenis bahan ferromagnetik dengan nilai χfd (%) kategori sedang yang menunjukkan campuran superparamagnetik (SP) atau bulir kasar bukan SP atau SP bulir <0.005 µm dan hasil karakterisasi TEM menunjukkan bahwa nanokomposit Fe3O4@SiO2 telah berhasil terbentuk formasi core-shell.
