Polyvinylidene fluoride (PVDF)

The study was evaluated and compared to commercial heterogeneous membrane in order to make cation exchange membrane set up the optimal preparing condition. The research findings show that ion exchange resin was added more than 40 wt% in order to show chemical properties of HPVDF higher than commercial heterogeneous membrane. But ion exchange resin was added less than 40 wt% in order to show mechanical properties of HPVDF higher than commercial heterogeneous membrane. According to conditions above, Electrical resistance was 1.83 Ω⋅cm-1, water uptake was 79%, ion exchange capacity was 1.60 meq/g, and burst strength was 0.97 MPa. Also The TDS remove efficiency was measured by approximately 40%.This article has no abstract. Keywords: sodium hydroxide; polyvinylidene fluoride (PVDF)
