POLYMER ADDITIVE COMPRISING ZWITTERIONIC MOIETIES FOR PVDF BASED MEMBRANES

摘要

The present invention pertains to composition suitable for manufacturing membranes based on vinylidene fluoride (VDF) polymers, to porous membranes thereof, to methods for their manufacture and to uses thereof, especially for the filtration of water phases. Said composition comprising vinylidene fluoride (VDF) polymers and polymer additives comprising zwitterionic moieties delivers outstanding hydrophilization performances of manufactured membranes.
