Abstract

This paper explores the impact of solution copolymerization of hydrophobic monomer (MMA and VAc) and hydrophilic monomer (AA and MAA) on casting membrane solution and PVDF membrane. Through experimental results and representations, it shows that, with NVP content proportion in monomer decreases, the viscosity of casting membrane solution decreases and it is in the form of instantaneous demixing in the pure water coagulation bath (except for Ml), with the average effective aperture distribution widens and MWCO increase; with NVP content proportion in monomer decreases, the viscosity of casting membrane solution and light transmission rate increases first and then decreases; membrane fracture surface structure exists in the form of large-scale finger hole; porosity, membrane flux and average effective aperture all increase first and then decrease, exerting relatively high reject rate on PEG series.
