Variations in the wettability of a PMR-351 laminate (polyimide and tetrafluoroethylene-hexafluoropropylene copolymer) film under the action of a low-frequency glow discharge plasma depending on the duration and conditions of the treatment was studied. For the modified films, the stability of contact angles {theta} upon film storage in air was studied. Experimental values of {theta} were used for calculations of the total free energy of the surface and its polar and dispersion components. Chemical and structural changes on the polyimide and the fluoropolymer surface of the film under the action of plasma were studied using the technique of multiple internal-reflection IR spectroscopy. A possible mechanism of these changes is suggested.
