Effects of Polysulfone (PSf) Support Layer on the Performance of Thin-Film Composite (TFC) Membranes
The performance of thin-film composite (TFC) membranes was related to the properties of support layers. In this study, polysulfone (PSf) membranes formed by the phase inversion process under various concentrations of PSf and polyvinylpyrrolidone (PVP) additive were used as support layers to prepare polyamide (PA) TFC membranes by the interfacial polymerization (IP). The effects of PSf and PVP c...
متن کاملPreparation and Physical Characterization of Sulfonated Poly (Ether Ether Ketone) and Polypyrrole Composite Membrane
Sulfoanted poly(ether ether ketone) membranes were prepared by the sulfonating agent sulfuric acid. These membranes were modifed by incorporating conducting polymer polypyrrole in order to increase the ionic conductivity and reduce the methanol transmission rate. The modifed composite membranes were then compared on the basis of ionic conductivity, methanol transmission...
متن کاملNanocomposite Based on Functionalized Gold Nanoparticles and Sulfonated Poly(ether ether ketone) Membranes: Synthesis and Characterization
Gold nanoparticles, capped by 3-mercapto propane sulfonate (Au-3MPS), were synthesized inside a swollen sulfonated poly(ether ether ketone) membrane (sPEEK). The formation of the Au-3MPS nanoparticles in the swollen sPEEK membrane was observed by spectroscopic and microscopic techniques. The nanocomposite containing the gold nanoparticles grown in the sPEEK membrane, showed the plasmon resonanc...
متن کاملMitigation of Arsenic from Water through Tailor-made Thin Film Composite (TFC) Membrane
Submit Manuscript | http://medcraveonline.com ‘mass poisoning’ in the world. It can exist in different form viz. As (III) and As (V) in natural water [1]. Human exposure to arsenic can take place through ingestion, inhalation or skin adsorption. High dose of arsenic can cause acute toxic effects including gastrointestinal symptoms (poor appetite, vomiting, etc.), disturbance of cardiovascular a...
متن کاملPolybenzimidazole block sulfonated poly(arylene ether sulfone) ionomers.
Novel ionomers based on polybenzimidazole block sulfonated poly(arylene ether sulfone) show excellent thermal properties. The ionic aggregation of sulfonic acid groups leads to well-developed phase separated morphology and thus high proton conductivity at wide humidity range, up to 65 mS cm(-1) at 90% relative humidity.
