Abstract (en)
[origin: WO0105492A1] Microporous membranes (10) comprising polyvinylidene difluoride and methods for making such membranes are disclosed. The membranes (10), which are not crosslinked and are not contacted with a strong alkali solution during manufacture, are wettable by aqueous solution even after repeated wetting and drying. The membrane includes a support (18) and surfaces (11) treated with a hydrophilic coating. Separately, such membranes are also useful in apparatus (60) for separating a biological fluid into two or more components.
