This paper presents a technology for applying copper and silver films to cotton fabrics by combining photochemical and chemical methods for the reduction of the compounds of these metals. The resulting metal-containing films have inherent electrical conductivity of metals. All the main processes described in the work were carried out by means of the compounds being sorbed by the surface of the fabric when they were wetted in appropriate solutions. The aim of the work was to study the application of electrically conductive composite copper films on cotton fabrics. The tasks to achieve this aim were to perform scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction analysis to confirm that as a result of the experiment, CuCl with a semiconductor ability was formed on the surface of the sample. The driving force behind the photochemical reduction of copper and silver halides on cotton surfaces is that, as a result of the photooxidation of cellulose molecules in the fabric, copper monochloride is first formed on the cotton surface. Subsequently, the process of obtaining silver particles based on semiconductor silver chloride obtained as a result of the transformation of copper monochloride was carried out. The physicochemical and photochemical processes leading to the formation of monovalent copper chloride, which provides sufficient adhesion to the substrate, are considered. It is shown that in this case, the oxidation of monovalent copper also occurs with the formation of soluble salts that are easily removed by washing. Since the proposed technology does not require special equipment, and the chemical reagents used are not scarce, it can be used to apply bactericidal silver films to various household items and medical applications in ordinary laundries or at home. This article examines an affordable and simple technology for producing metal films on a cotton surface due to the presence of disadvantages (time duration, high temperature, scarce reagents, special installations, etc.) of a number of well-known methods in the production of chemical coatings.

The article investigates the process of applying the conductive layer on isotactic polypropylene modified by the radiation grafting monomer for improving the wettability of the surface. Presented IR spectra, the results of measuring the contact angle of the modified material indicate the improved surface hydrophilicity. The degree of grafting functional groups to the surface of isotactic polypropylene is determined. A scheme of gradual modification of polypropylene surface is presented. As the primary layer for the polymer metallization, copper-phosphorus film may be used. Copper-phosphorus films were obtained by reduction of copper compounds with phosphine gas. Experimental results show that the copper phosphide is electrically conductive coating and imparts an increased hardness.

Статья посвящена поверхностной модификации изотактического полипропилена путем радиационной прививки функциональных полярных групп с целью последующей металлизации полимерного материала. Представленные ИК-спектры, результаты измерения краевого угла смачивания модифицированного материала указывают на улучшение гидрофильности поверхности. Установлена степень прививки функциональных групп к поверхности изотактического полипропилена. Предложена схема поэтапного модифицирования поверхности полипропилена. Для получения токопроводящего слоя на поверхности модифицированного полипропилена использован низкотемпературный газо-фазный метод нанесения электропроводящих пленок фосфида меди. Приведены экспериментальные результаты, показывающие, что фосфид меди обладает электрической проводимостью и придает покрытию повышенную твердость.
