Surface modifications of polyaniline films by graft copolymerization

摘要: Both pristine and argon plasma treated emeraldine (EM) base films were subjected to near-UV light-induced graft copolymerization with acrylamide, sodium styrenesulfonate (NaSS) acrylic acid (AAc). It was found that in each case, the density of surface grafting is enhanced by treatment. Surface three polymers also leads a more hydrophilic film. Grafting NaSS AAc readily gives rise self-doped or self-protonated EM structure. However, substantial proportion grafted protonic groups at remains free for further modification functionalization
