متن کاملA carbon nanotube-infused polysulfone membrane with polyvinyl alcohol layer for treating oil-containing waste water
A carbon nanotube (CNT) integrated polymer composite membrane with a polyvinyl alcohol barrier layer has been prepared to separate oil from water for treatment of oil-containing waste water. The CNTs were synthesised using chemical vapour deposition, and a phase inversion method was employed for the blending of the CNTs in the polymer composite solution for casting of the membrane. Relative to ...
متن کاملNafion-layered sulfonated polysulfone fuel cell membranes
Sulfonated polysulfone (SPSU) with high ion exchange capacity (IEC) and ion conductivity was synthesized through deep sulfonation of polysulfone using the trimethysilyl chlorosulfonate as sulfonation agent. The silicon-containing compounds formed during the synthesis of SPSU were completely removed from the SPSU by simple evaporation. Water swelling, ion exchange capacity, conductivity and fuel...
متن کاملComposite Electrolyte Membranes from Partially Fluorinated Polymer and Hyperbranched, Sulfonated Polysulfone
Macromolecular modification of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF) was done with various proportions of sulfonic acid terminated, hyperbranched polysulfone (HPSU) with a view to prepare ion conducting membranes. The PVDF-co-HFP was first chemically modified by dehydrofluorination and chlorosulfonation in order to make the membrane more hydrophilic as well as to introduce uns...
متن کاملCarbon nanotube/polysulfone composite screen-printed electrochemical enzyme biosensors.
The fabrication, evaluation and attractive performance of multiwall carbon nanotube(MWCNT)/polysulfone biocomposite membrane modified thick-film screen-printed electrochemical biosensors are reported. The fabricated carbon nanotube/polysulfone (CNT/PS) strips combine the attractive advantages of carbon nanotube materials, polysulfone matrix and disposable screen-printed electrodes. Such thick-f...
