Preparation and Characterization of PVDF/Alkali-Treated PVDF Blend Membranes

Article Preview

Abstract:

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 hydrophilicity increased with increase of the fraction of alkaline treated PVDF powder. The fouling potential also decreased with the increase of the fraction of alkaline treated PVDF powder.
