摘要

A series of cellulose acetate membranes were prepared by using formamide as additive

and then were hydrolyzedin 4 wt% aqueous NaOH solution for 8 h to obtain regenerated cellulose membranes. The dependence of degree ofsubstitution

structure

porous properties

solubility and thermal stability on hydrolysis time was studied by chemical titration

Fourier transform infrared spectroscopy

scanning electron microscopy

wide-angle X-ray diffraction

and differential scanning calorimetry

respectively.The results indicated that the pore size of the regenerated cellulose membranes was slightly smaller than that of cellulose acetate membrane

while solvent-resistance

crystallinity and thermostability were significantly improved.This work provides a simple way to prepare the porous cellulose membranes

which not only kept the good pore characteristics of cellulose acetate membranes

but also possessed solvent-resistance

high crystallinity and thermostability.Therefore

the application range of cellulose acetate membranes can be expanded.
