Abstract

Asymmetric BLEND hollow fibre membranes were made from a new castng dope containing poly(vinylidene fluoride) (PVDF)/thermoplastic polyurethane (TPU)/ N,N-dimethylacetamide (DMAc )/polyvinylpyrrolidone (PVP). The separation property, microstructure, crystalline phase of membranes, and membrane strength were characterized by bovine serum albumin (BSA) retention experiments, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy- attenuated total reflection (FTIR-ATR), differential scanning calorimetry (DSC) and tensile testing, respectively. PVP at low concentration (≤3 wt%) was a significant demixing enhancer which thermodynamically controlled the phase inversion process, improved flux, reduced α-form crystal structure, and decreased crystallinity of PVDF in membranes. At high concentration of PVP (>3 wt %) due to viscosity buildup, kinetic hindrance overwhelmed the thermodynamic factor which suppressed the formation of macrovoids, reduction of flux, and increase in crystallinity of PVDF in membranes.
