Gilding arc plasma is a non-equilibrium phase and can be generated at atmospheric pressure. Surface treatments are a popular application of this form of plasma because of its relatively low temperature. Polytetrafluoroethylene (PTFE) film is naturally hydrophobic with low surface energy caused by its very stable covalent carbon bonds. In this study, the surface of PTFE film was made hydrophilic by treating it with gliding arc plasma. Tests were conducted with argon, oxygen, air, and nitrogen as discharge gases to test the effects of different species of active radicals formed by the arc. The treated film surfaces were analyzed after surface treatment with different gases and for different times, and the contact angle of the PTFE was 80° before treatment. OH radicals from the ambient air were generated by the gliding arc and these attached to the surface of PTFE. However, the contact angle increased again over time, and when oxygen or nitrogen were used during the plasma treatment, the PTFE surface returned to its original hydrophobic state after about 8 days. The OH radicals attached to the surface likely reacted with ambient air and left the surface over the course of this process.
