Improvement of adhesion properties of the surface of polyethrafluoroethylene films in the glow discharge

There is an acute problem of increasing the service life of machines and mechanisms operated in extreme climatic conditions. One of the promising methods of solution is the use of polymer functional coatings that can withstand long-term destructive factors. Among them, special attention is paid to PTFE (polytetrafluoroethylene, PTFE) due to its unique properties, such as heat, frost resistance, low coefficient of friction, etc. [1]. However, a significant disadvantage is the low adhesion to most materials, which makes it difficult to use as special coatings (anticorrosive, electrical insulating, anti-icing, heat-resistant, self-lubricating, etc.).
