Abstract

The processes in polymer films based on polypropylene containing fluorinated additives during modification of films in corona discharge plasma are studied. The chemical composition, relief, adhesion and deformation properties of the film surface before and after modification in plasma were studied using the methods of X-ray photoelectron spectroscopy and atomic force microscopy. It has been established that in films under the influence of corona discharge plasma migration of the fluoropolymer additive to the surface occurs. In this case, the chemical composition and structure of the film changes, and local structures containing oxygen, fluorine and carbon atoms are formed on the surface. Local structures have an electrical resistance that is different from the electrical resistance of the surface of the original film. Plasma modification leads to an improvement in the elastic and adhesive properties of the polypropylene film surface.

低温电晕放电等离子体改性过程中添加剂迁移对聚丙烯基薄膜表面特性的影响

研究了含有氟化添加剂的聚丙烯聚合物薄膜在电晕放电等离子体中改性的过程。使用 X 射线光电子能谱和原子力显微镜方法研究了薄膜在等离子体中改性前后表面的化学成分、浮雕、附着力和变形特性。结果表明，在电晕放电等离子体的影响下，薄膜表面的含氟聚合物添加剂会发生迁移。在这种情况下，薄膜的化学成分和结构会发生变化，表面会形成含有氧原子、氟原子和碳原子的局部结构。局部结构的电阻与原始薄膜表面的电阻不同。等离子改性可改善聚丙烯薄膜表面的弹性和粘合性。

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.
