In recent years, atmospheric pressure plasma jets(APPJs) have been widely studied for the processing of a variety of materials and biomedical applications. In order to study the effects of different forms of power supplies on APPJs and their treatment, we applied a self-made high-frequency high-voltage pulse power supply to generate APPJs, and compared the APPJs with those generated by the AC power supply under the same conditions, including parameters such as the current, shape, temperature, and emission spectrum. Additionally, we compared the speed of improving the surface hydrophobicity of contaminated high temperature vulcanization(HTV) silicone rubber treated by APPJs generated by different forms of power supplies. Studies show that, with the same peak voltage and frequency, the APPJs generated by pulse power supply have 1.4 times length, 50 times peak current and about twice emission spectrum compared to those generated by AC power supply. Simultaneously, they produce less heat and improve the surface hydrophobicity of contaminated HTV in a shorter time. It can clearly be seen that the APPJs generated by pulse power supply have better parameters and treating effect than those generated by AC power supply.
