This paper presents an experimental study of the use of an argon ferromagnetic enhanced inductively coupled plasma (FM ICP) to improve the wettability of the polytetrafluoroethylene (PTFE) surface. The wettability of the PTFE surface treated with the FM ICP increased with increasing treatment time and power density. PTFE treatment at a power density of 0.12 W/cm3 for 32 min led to a decrease in water contact angle (CA) to 59◦. SEM images of the surface and profilometry data show a decrease in PTFE surface roughness with increasing treatment time. XPS data indicate surface defluorination, the formation of new C–O and C–N bonds, and the absence of any compounds with metal atoms. Therefore, the obtained data on plasma modification of the PTFE surface can be considered free from the influence of metal atom contamination. The study of the aging of plasma-modified PTFE surfaces showed an increase in CA to 78◦ after 10 days of storage under laboratory conditions. Thus, the FM ICP is suitable for modifying the PTFE surface to improve its wettability without contamination of the surface with atoms of metal electrode and walls elements
