摘要: Abstract Foils of polyethylene, polypropylene and polyethylene terephthalate are exposed to low-pressure plasmas. The plasma is produced by microwaves ( f =2.45 GHz) at the electron cyclotron resonance, with densities about 10 11 cm -3 temperatures between 2 4 eV. Oxygen hydrogen used here for treatment a pressure typically 3 Pa. Quartz-like polyethylene-like thin films on polymers as adhesion agents. power adhesive measured pull-off tests. strongly increases treatment, factor 20 after few seconds. surface tension polymer foils using Cahn tensiometer. It shown that polar part tested whereas dispersion only weakly influenced. correlated. surfaces investigated scanning microscopy infrared spectroscopy.
