摘要
Dielectric barrier discharge (DBD) is a commonly used plasma surface modification technique, and the power parameters play a crucial role in influencing the modification results. Electrical properties of DBD pulses were studied by varying both power and frequency. Additionally, how these electrical properties influence the chemical and topographical alterations in polyethylene surface modification was investigated. In terms of chemical changes, we found that higher power supply significantly enhances the modification result, whereas alterations in frequency do not exert a substantial impact. Concerning topographical changes, increased power supply yielded similarly effective results, while heightened supply frequency improved the modification result due to the enhanced uniformity of discharge pulses. Regarding hydrophobicity, power supply exerts a more significant and pronounced influence compared to frequency.
