摘要

2'-(2-Pyridyl)ethyl methacrylate (2-PEMA) synthesized in our laboratory was grafted onto the surface of polyacrylonitrile (PAN) ultrafiltration membranes by plasma-induced graft copolymerization. He plasma was used to activate the surface of PAN membranes before the grafting reaction. The amounts of peroxides created by plasma treatment were determined using 2,2-diphenyl-1-picrylhydrazine (DDPH). Influences of plasma treatment power, time, monomer concentration, presence of inhibitor, and solvents on polymerization were investigated. Surface functionalization was characterized by FTIR-ATR, ESCA, SEM:, and water-contact angles. Grafting yield was shown to increase with the monomer concentration and if a mixture of H2O/CH3OH was used. Hence, it was possible to snow that plasma treatment was a good technique to introduce ligands with coordinating properties by mortifying the surface of the PAN membranes.
