Modification of Polymer Surface by Corona Discharge and the Subsequent Graft Polymerization of Acrylamide

This study is concerned with the graft polymerization of acrylamide onto the surfaces of polyethylene and polyethylene terephthalate films treated with on corona discharge. In the case, peroxides formed by the corona discharge treatment are likely to be the species responsible for initiating the graft polymerization. This treatment produced a continuous charge in wettability and also amid group density on the polymer surface, as evidenced by water contact angle measurement, Fourier-transform infrared spectroscopy in the attenuated total reflectance mode, and electron spectroscopy for chemical analysis. Both of the merely corona-treated film and the subsequently grafted film are discussed as a function of time after treatment and water washings.
