Polyvinyl chloride (PVC) sheets were treated with corona discharge to produce peroxy radicals on the surfaces. The peroxy radicals formed on the PVC surfaces were subsequently used as initiators for the graft polymerization of acrylic acid or acrylamide in an aqueous solution. Introduction of acrylic acid and acrylamide on the PVC sheet could be confirmed by the observation of carbonyl and primary amine absorptions based on carboxylic acid and amide, respectively. The water contact angle of PVC sheet was constant, irrespective of time, while corona-treated and functional monomer-grafted PVCs were slowly increased with time, showing the rearrangement of surface polar groups in air condition. The water contact angle of PVC sheet was decreased by corona treatment, and further decreased by the grafting of acrylic acid and acrylamide , indicating increased hydrophilicity of the modified surfaces. The half-life periods of surface voltage on acrylic acid- (62 sec) and acrylamide-grafted PVC (147sec) were significantly decreased when compared to those on PVC (3,115 sec) and corona-treated PVC (463sec). These results mean that acrylic acid- and acrylamide-grafted PVCs could be used as the antistatic sheets. |
