The work was devoted to the development of technology for applying metal coatings to the surface of polypropylene products. At the same time, the main stages of the technology were carried out using the influence of electromagnetic waves of light radiation. So, to obtain an electrically conductive silver layer, after mechanical treatment, etching and activation, the polymer was immersed for several minutes in a solution containing 10-20 g/L of silver nitrate and equivalent amounts of ascorbic acid, and a thin layer of solution was obtained on the surface of the polymer. A sample with such a sorption film was exposed to electromagnetic waves of light radiation at a flux density of 700-1100 W/m. The small thickness of the sorption film facilitated the penetration of these waves directly onto the polymer surface and ensured the photochemical process of silver reduction with the formation of active centers. At the same time, electromagnetic waves acting on ascorbic acid transferred it to an excited state. As a result, the chemical reduction of silver in the space between the active centers became possible. In this case, the film obtained within 15-20 min had the necessary electrical conductivity. The suitability of these films for galvanic metallization of the polymer surface was shown.
这项工作致力于开发在聚丙烯产品表面施加金属涂层的技术。同时，该技术的主要阶段是利用光辐射的电磁波的影响来进行的。因此，为了获得导电银层，在机械处理、蚀刻和活化之后，将聚合物浸入含有10 - 20 g/L硝酸银和等量抗坏血酸的溶液中几分钟，从而在聚合物表面获得一层薄溶液。具有这种吸附膜的样品在通量密度为700 - 1100 W/m²的光辐射电磁波下曝光。吸附膜的小厚度有助于这些波直接穿透到聚合物表面，并确保银还原的光化学过程以及活性中心的形成。同时，作用于抗坏血酸的电磁波将其转移到激发态。结果，在活性中心之间的空间中银的化学还原成为可能。在这种情况下，15 - 20分钟内获得的膜具有所需的导电性。展示了这些膜对于聚合物表面电镀金属化的适用性。
