In recent years, low-temperature atmospheric-pressure plasma has attracted attention for applications such as cancer therapy, wound healing, and surface modification of biomedical materials. Short-lived reactive oxygen species (ROS) generated by plasma are considered to be involved in the oxidation and polymer surface modification. In this study, we evaluated the effect of frequency on the PET surface modifiaction. The frequency between 1 and 15 kHz was varied, and the water contact angle was measured for either plasma-treated and untreated PET surface.
