Abstract: The He cold plasma excited by microwave was used to activate the surface of polyethylene(PE). It resulted in forming of active sites on the surface and was followed by graft reaction with methyl methacrylate(MMA). The MMA-grafted samples were shown to be more hydrophilic than of untreated one. The influence of MMA conentration, microwave power and plasma treatment time on the graft degree and wettability for MMA-grafted PE were also studied. A coincidence of graft degree with wettability of PE films was found. The optimal operation condition was also advice, that is, MMA concentration, microwave power, and plasma treatment time were 0.1 mol/L, 200 W and 2.5 min, respectively.

Key words: Microwave plasma, Polyethylene, Surface grafting, Methyl methacrylate
