The Effect of DC Discharge on the Properties and Surface Structure of Polyphenylene Oxide Films
Abstract—The effect of low-pressure direct current discharge on polyphenylene oxide films was studied. Filtered atmospheric air was used as the working gas. It was shown that plasma treatment leads to significant hydrophilization of the polymer surface during treatment at the cathode and anode. The storage of modified films in air leads to a decrease in hydrophilicity, which is more characteristic of films treated at the anode. The change in the chemical structure of plasma-modified samples was studied by X-ray photoelectron spectroscopy and the formation of a significant amount of oxygen-containing groups was shown during plasma treatment of films. The atomic content of oxygen increased to a greater extent after treatment at the anode. Using atomic force microscopy, the change in film morphology after exposure by plasma was studied and a significant increase in their roughness was established. The modified films had significantly higher selectivity of gas permeability for CO2/CH4, CO2/N2 and O2/N2 vapors without reducing the flow of CO2 and O2 relative to the initial values.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
