用于聚四氟乙烯表面处理的重复频率高压脉冲电源

采用自行研制的μs级重复频率高压单极性脉冲电源，应用于聚四氟乙烯(PTFE)膜表面改性，研究脉冲放电等离子体对PTFE薄膜表面改性的作用规律。测量处理前后PTFE薄膜表面的水接触角，结果显示，在特定的脉冲参数及更严格的对比条件下其平均水接触角从112°下降到85°，PTFE薄膜表面亲水性改善效果非常显著。脉冲电源采用脉宽调制控制方式，通过逆变升压及波形整形，得到脉冲电压幅值0~20 kV、重复频率0~20 kHz、脉宽5~15 μs、上升沿500 ns~2 μs、下降沿大于20 μs的单极性脉冲。

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 μs, a pulse rise time of about 1-3 μs, 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°.
