通过Wilhelmy吊片法研究了CF4／CH4混合气体等离子体处理的PET浸水表面的动态行为．结果表明，处理后的PET浸水后表面增水性下降，这是由于表面含氟基团向体相的高速翻转及含氟链段向体相缓慢迁移的缘故．
The dynamic behavior of PET flooding treated with CF4 / CH4 mixed gas plasma was studied by Wilhelmy suspender method. The results showed that the surface water-repellency of treated PET decreased after water immersion, which was attributed to the high-speed turnover of fluorine-containing groups on the surface and the slow migration of fluorine-containing segments to the bulk.
