摘要/Abstract

摘要： 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.

关键词: Wilhelmy吊片法, CF₄/CH₄等离子体, 动态接触角, 滞后效应

Abstract: 篢he dynamic behavior of PETsurface modified with CF₄/CH₄ plasma was investigated by the dynamic contact angle method (Wilhelmy Plate Method) through water immersion.Some of experimental data were given and explained in terms of turning-over models,indicative of the motion of the containing-fluorine surface groups.

Key words: Wilhelmy plate method, CF₄/CH₄ plasma, Dynamic contact angle, Hysteresis effect
