N2 - Hydrophilic surface modification of ceramic membrane was performed by grafting polymerization using acrylic acid. The modified membrane was characterized by FT-IR. It indicated that poly (acrylic acid) (PAA) was successfully grafted onto the membrane surface. The effects of polymerization conditions on the performances of the pH-responsive membrane were investigated. The results showed that pH sensitivity of the grafted membranes increased with monomer concentration, as the monomer concentration < 131.25 g/L. The anti-fouling performances for the different PAA-grafted membranes were assessed by the filtration of Bovine serum albumin solution (BSA). All modified membranes showed higher rejection and lower permeability than unmodified membrane for the BSA solution. PAA-grafted membranes showed higher relative flux, flux recovery, and lower reduction of flux, which revealed that the anti-fouling performance of PAA-grafted membranes was improved. Furthermore, the change of pH can result in a varying fouling, and PAA-grafted membranes showed the smallest fouling at pH 8.0. Therefore, PAA-grafted membranes may resist protein fouling at high pH application.
