Abstract
In order to explore the effect of the pulse power discharge and surface processing on polytetrafluoroethene(PTFE) film, we used the means of pulse transformer to set up a repetitive rating high voltage pulse power with the semiconductor solid switch IGBT, and finally achieved the target, a variable voltage amplitude of 15-20 kV, a pulse width of 10-15 s, a pulse rise time of about 1-3 s, and a variable repetitive rating 10-15 kHz. Meanwhile, we had a measurement for the water contact angle of the PTFE film before and after processing, and found that the water contact angle decreased from 112 to about 85.
