Polyacrylonitrile (PAN) membrane has been prepared by phase inversion method and subsequently modified by surface grafting polymerization of acrylic acid (AA). The influence of the surface modification on membrane properties hasbeen investigated through the surface characteristics and separation performance. The experimental results indicated that the grafting polymerization of AA leads to the reduced membrane skin pore size and the lower surface roughness. The separation performance of the modified PAN membrane is highly impoved due to the enhanced flux and the higher protein (BSA) retention; the antifouling property of membranes is also improved compared with that of the unmodified one...
