Plasma Irradiation to Poly(acrylic acid) Brushes fabricated on Polystyrene Substrate and its Characterization

抄録

The effects of argon plasma irradiation on pAAc-grafted PS substrate were investigated. The argon plasma irradiation caused the efficient decarboxylation in pAAc brushes so that the surface hydrophilicity was significantly changed. The protein antifouling properties on pAAc-grafted PS substrate were lost even by short plasma irradiation so that the surface was changed to highly favorable for protein adsorption. These results are useful for controlling the protein adsorption onto pAAc-grafted materials and expected to be used for the development of microarray such as protein and cell array using pAAc-grafted PS as a substrate.
