摘要: It has been found that treatment in dc discharge results a substantial and time-invariant increase the surface energy of poly(vinylidene fluoride) films. This effect is obviously due to formation oxygen-containing groups on polymer surface, fact corroborated by Fourier-transform IR spectroscopy X-ray photoelectron data. shown more effective altering contact properties than low-frequency glow discharge.
