Abstract

In this study, four different types of poly(vinylidene fluoride) (PVDF) membranes were prepared by blending with poly(vinylidene fluoride)-graft-poly(sulfopropyl methacrylate) (PVDF-g- PSPMA) or/and potassium perchlorate (KClO₄). Blending PVDF with PVDF-g-PSPMA and KClO₄ allowed the membrane to have hydrophilicity and smooth surface morphology. For example, blending of PVDF-g-PSPMA and KClO₄ (A4) showed approximately 13° lower water contact angle and about 23-nm more smooth surface morphology in comparison with no additives (A1) and blending of PVDF-g-PSPMA only (A2), respectively.
