Hydrophobicity Enhancement of Poly(vinylidene fluoride-co-hexafluoropropylene) for Membrane Distillation
Keywords:
PVDF-co-HFP membrane, surface modification, membrane distillation, contact angleAbstract
A Poly (vinylidene fluoride-co-hexafluoropropylene), (PVDF-co-HFP) hollow fiber membrane was prepared by phase inversion method using different concentrations of PVP as a pore former additives in the dope solution. Surface modification was done using a formic acid through immersion technique. It was observed that the contact angle for all membranes increased due to the surfaces modification (10% of hydrophobicity increment).This study shows that the hydrophobicity of (PVDF-co-HFP) hollow fiber membrane can be enhanced via formic acid surface modification process.References
