| Summary: | Poly (vinylidene fluoride-co-hexafluoropropylene), (PVdF-co-HFP) hollow fibre 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). Based on SEM and FTIR analysis
the study found that the hydrophobicity of (PVdF-co-HFP) hollow fibre membrane can be
enhanced via formic acid surface modification process |
