Abstract

The invention provides a process for preparing a metal silver micropattern on a polymeric material surface. High-energy ultraviolet light is employed to radiate on different polymeric substrate material surfaces in order to modify the polymeric substrate material surfaces, wherein a radiation time is controlled at 10-20 min; meanwhile, during the ultraviolet light radiation process, photographic masks are covered on polymeric substrate material surfaces to realize micro area modification on polymeric substrate material surfaces; then a silver coating solution is employed to carry out a selective silver coating on polymeric substrate material surfaces. According to the invention, ultraviolet light is directly employed to radiate on polymeric material surfaces in order to modify material surfaces and generate functional groups that are conducive to sedimentation of metal silver. Compared with a process that a monomolecular film is grafted on a substrate material surface and treated by a sensitizer and an activator successively, the process of the invention guarantees a uniform functionalization on the substrate material surface and substantially simplify the substrate material surface treatment technology; besides, silver coating patterning is realized while keeping high fidelity of the silver coating pattern.
