Biocompatibility and Antimicrobial Activity of Some Quaternized Polysulfones

Maximizing Performance of the Membranes Based on Quaternized Polysulfone/Polyvinil Alcohol for Biomedical Applications: Rheological Investigations

The rheological response of blends obtained from quaternized polysulfone and polyvinyl alcohol in N-methyl-2pyrrolidone as against structural peculiarity of polymers from the blend, composition of polymer mixtures, as well as the types of interactions were investigated. Results show that the variation of polyvinyl alcohol composition in the studied system determines changes of the rheological p...

Functionalized Polymeric Membranes for CO2 Capture

Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

Development and Characterization of Chitosan based Polymeric Hydrogel Membranes
