Phase Inversion Process

The regenerated cellulose carbamate membranes were prepared by the phase inversion process. The structure and properties of the regenerated cellulose carbamate membranes were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD) and scanning electron microscopy (SEM). Besides, the effects of the casting solution concentration and the coagulation bath concentration on the mechanical property of regenerated cellulose carbamate membrane were discussed.

Phase Inversion Process

Porous asymmetric PVDF membranes were prepared by the phase inversion process induced by a nonsolvent. The effect of pore-forming hydrophilic additives on the membrane morphology and transport properties was investigated. It was found that membranes prepared with hydrophilic polymer additives can offer higher pure water flux, higher porosity and lower pepsin rejection. PEG 10 000 can be used as a good pore forming additive to prepare PVDF membrane with higher pure water flux and relatively high pepsin rejection.

Ultrafiltration Process

Poly(amic acid) prepared from 3,3',4,4'-benzophenonetetracarboxylic dianhydride and bis(4-aminophenyl) ether was used for preparation of microporous membranes by the phase inversion process. Membranes coagulated in acetic anhydride were brittle but usable for ultrafiltration. Coagulation of the poly(amic acid) in water or lower alcohols and subsequent thermal cyclocondensation led to extremely brittle polyimides, which limits their use for ultrafiltration process.
