Abstract Photochemical processes in thin surface layers of solutions of compounds of the copper subgroup elements leading to the formation of dispersed metal particles on the surface of dielectrics are investigated. It is shown that dispersed particles of elemental gold are formed on dielectrics moistened with AuCl3 solution and exposed to sunlight. At the same time, there is no need to use any chemical reducing agents. On cotton fabrics moistened with solutions of AgNO3, CuBr2, when exposed to sunlight, silver and copper monohalides are formed, respectively. These processes take place with the participation of terminal cellulose molecules and also do not require the use of chemical reducing agents. In addition, it was found that copper monohalides can be converted into elemental copper particles by a photochemical reaction involving ascorbic acid. Examples of metallization of a number of dielectrics using photochemical activation using sunlight are given.

通过光化学工艺将金属涂层应用于介电材料

摘要 研究了铜亚族元素化合物溶液的薄表面层中导致在电介质表面形成分散金属颗粒的光化学过程。结果表明,元素金的分散颗粒在用 AuCl3 溶液润湿并暴露在阳光下的电介质上形成。同时,无需使用任何化学还原剂。在用 AgNO3、CuBr2 溶液润湿的棉织物上,当暴露在阳光下时,分别形成一卤化银和一卤化铜。这些过程在末端纤维素分子的参与下进行,也不需要使用化学还原剂。此外,发现一卤化铜可以通过涉及抗坏血酸的光化学反应转化为元素铜颗粒。给出了使用太阳光进行光化学活化对许多电介质进行金属化的例子。
