摘 要: | 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0~20kV、重复频率0~20kHz、脉宽5~15μs、上升沿500ns~2μs、下降沿大于20μs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 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. |
