Paper Title:
Preparation and Characterization of PVDF Hydrophobic Membrane
  Abstract

Polyvinylidene fluoride (PVDF) hydrophobic membrane has been prepared by phase inversion method. The effects of concentration of PVDF, different processes of preparations, and different surface roughness on hydrophobic capability of membrane surface (water contact angle, WCA) have been investigated. The results showed that, hydrophobic ability of PVDF membranes decreased with the increasing concentration of PVDF. WCA of membrane prepared by was increasing. Membrane surface hydrophobic ability increased with the increasing surface roughness. The contact angle of membrane comes to 141° with dry process and 10% PVDF concentration.
