摘要

The effect of low-temperature, low-pressure direct current discharge plasma (with air as plasma gas) on addition poly(5-ethylidene-2-norbornene) films was studied. X-Ray photoelectron spectroscopy study revealed significant changes in the chemical structure of the sample surfaces, in particular, the appearance of numerous oxygen-containing groups and a rather high degree of hydrophilization. Storage of the modified films in air under ambient conditions leads to a decrease in surface hydrophilicity. An atomic force microscopy study showed that plasma treatment causes an increase in the surface roughness. Surface modification leads enhances the permselectivity for CO2—CH4, CO2—N2, and O2—N2 gas pairs without reducing the CO2 and O2 flow relative to the initial values.
