Problems solved by technology

[0003] In recent years, there are also literature reports on polymer materials such as PET, PI [POLYMERS FOR ADVANCED TECHNOLOGIES, 2008, 19:335~341], PS [Journal of Alloys and Compounds, 2009, 473:206~211], P(AN- GMA) and PGMA and other substrates to realize electroless silver plating, but what these documents report is all the silver plating of large area on the material surface, but the report of realizing silver plating patterning on the material surface is rare; Before silver, it is often necessary to carry out complex treatment or modification of the material, such as grafting a monomolecular film on the surface of the material, or sensitizing and activating the base material before silver plating [Acta Chemie Sinica, 2002, 60 (4) :627~632], these silver plating pretreatments make the silver plating process complicated

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.

Description

technical field [0001] The invention relates to the field of surface and interface modification technology of inorganic chemistry and organic polymer materials, in particular to a process method for preparing metallic silver micropatterns on the surface of polymer materials. Background technique [0002] With the rapid development of material science, the mechanical properties of materials can basically be met through material modification. In this situation, the properties of material surfaces have attracted more and more attention from researchers. Therefore, an important development direction in the field of materials at the current stage is the micro-control and micro-processing of the surface properties and structures of the material surface on the submicron scale. The development of many modern technologies comes from the construction and miniaturization of new microstructures. The construction of new microstructures or the miniaturization of existing structures has ...
