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
