Abstract:

In order to improve the adhesion performance of polytetrafluoroethylene (PTFE) film, this research studied the effect of oxygen plasma treatment on the stripping strength and water contact angle of the film surface, and compared the adhesive strength of films treated by oxygen, nitrogen and argon plasma. In addition, the changes of surface element, morphology and roughness were measured by means of X-ray photoelectron spectroscopy, scanning electron microscopy and atomic force microscopy. The results show that the stripping strength is increased by 539.8% and the contact angle is increased by 11.4° (up to 120.4°) when the PTFE film is treated with nitrogen plasma. When the discharge magnitude is below 36 kJ, the stripping strength of the oxygen-treated PTFE film increases exponentially with the increase of discharge power. When the discharge magnitude is higher, the pattern of lotus leaf with the concave and convex grooves is formed on the PTFE film surface, and the shape of lotus leaf of PTFE film determines the film adhesion and hydrophobicity.

Key words: polytetrafluoroethylene film, plasma treatment, film modification, adhesion performance, surface etching
