Polysulfone membranes for CO2/CH4 separation: State of the art

The world market for CO2/CH4 separation using membrane technology is getting bigger and polysulfone (PSf) is one of the most widely investigated polymer membrane materials. However, the existing PSf membranes performances are insufficient to fully exploit these opportunities. Therefore, modification that would produce membrane that fit the needs of target separation performances is a main issue...

Nafion-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...

Advances in Polysulfone-Based Membranes for Hemodialysis

The polysulfone-based membrane has been used in hemodialysis (HD) and it is continuously developed to maintain its sustainability on the subject of biocompatibility. During the polysulfone-based membrane development, several parameters should be considered to improve the membrane performances, such as excellent biocompatibility, appropriate ultrafiltration rate, and effective clearance of the t...
