## Abstract Hydrophilic ultrafiltration membranes have been prepared by blending cellulose acetate (CA) as a matrix polymer with increasing concentrations of poly(vinylpyrrolidone) (PVP) using __N,Nβ²__βdimethylformamide as the solvent. It is observed that the presence of PVP beyond 50 wt % in the c

In the present work, N,N-dimethylformamide was chosen as a cosolvent of cellulose acetate (CA) and polyacrylonitrile (PAN). The blend solution showed appropriate viscosity, good membrane-forming property and relative stability.
A modified microfiltration membrane has been prepared by blending a matrix polymer with a functional polymer. Cellulose acetate (CA) was blended with polyethyleneimine (PEI), which was then crosslinked by polyisocyanate, in a mixture of solvents. In the membrane, PEI can supply coupling sites for li
