Abstract:
      In order to obtain the metal-coated fiber with high temperature resistance and long service life, Cu-based coating was plated on quartz fiber surface by electroless plating and studied by material characteristic parameters measurement. SEM, EDS, XPS and Raman were used to characterize the microstructure of graphene sheet and cu-based coating. Electrochemical workstation and nano indentation instrument were used to test the properties of metal coating. The bonding properties of Cu-based coating and fiber substrate were analyzed by thermal shock method. The results show that compared with Cu coating, Cu-graphene coating has more compact structure, better quality and fine grain, with the hardness and elastic modulus increased by 33.5% and 34.0% respectively. The corrosion potential Ecorr of Cu-graphene coating increased by 32.3%, and the corrosion current icorr decreased by 22.5%. The corrosion resistance of Cu-graphene coating is obviously improved. The surface of quartz fiber is electroless coated with Cu metal coating, which can overcome the problem of burning out due to excessive local temperature of optical fiber cladding optical filter in practical application. The coating has no blocking on signal transmission inside the optical fiber. Graphene can improve the forming quality of optical fiber surface coating, improve corrosion resistance and other properties, which is of great significance to improve the service life of optical fiber.
