THE USE OF PHOTOCHEMICAL PROCESSES FOR METALLIZATION OF POLYETHYLENE

In the last fifty years, the process of metallization of polymers has become widespread in technology. Metallization of polymers involves obtaining a new functional material that hides polymer defects under a metal layer. Having improved a number of disadvantages of the polymer, a new material was obtained with other features not characteristic of polymer and metal. Thanks to their new properties, metallized polymers are used in many areas (automotive, energy, electronics, marine, aviation, space, etc. in everyday life).
This article studies photochemical processes in thin sorption films of solutions of compounds of elements of the copper subgroup, leading to the formation of dispersed metal particles of polymers. It has been shown that dispersed particles of elemental gold are formed in polymers placed in an AuCl₃ solution and exposed to sunlight. In this case, there is no need to use any chemical reducing agent. Silver and copper mono connections are formed, respectively, under the influence of sunlight in polymers wetted with solutions of AgNO₃, CuBr₂. These processes occur with the participation of the last polymer molecules and do not require chemical oxidizing agents. In addition, it was discovered that copper halides can be converted into elemental copper particles by a photochemical reaction in the presence of ascorbic acid. Examples of metallization of polymers using photochemical activation by sunlight are given.
