Towards permanent hydrophilic PVDF membranes. Amphiphilic PVDF-b-PEG-b-PVDF triblock copolymer as membrane additive

European Polymer Journal, 2020
Poly(vinylidene fluoride) (PVDF) ultrafiltration membranes were prepared by non-solvent-induced phase separation (NIPS) using a blend of a new amphiphilic PVDF-based triblock copolymer (PVDF-b-PEG-b-PVDF) and high molar mass PVDF. During the phase inversion step, the triblock copolymer acts both as a pore forming and surface modifying agent.

Preparation and Characterization of PVDF/Alkali-Treated PVDF Blend Membranes [PDF]

Advanced Materials Research, 2012
Poly(vinylidene fluoride) (PVDF) powder was treated with aqueous sodium hydroxide to obtain partially defluorinated fluoropolymers with expected properties such as improved hydrophilicity and fouling resistance (used as membrane material). The effects of concentration of aqueous sodium hydroxide were investigated. The results showed that the membrane’s
