为制备耐高温、寿命长的金属镀层光纤,利用化学镀技术在石英光纤表面制备Cu基镀层.同时将石墨烯片层材料引入镀液,制备了Cu-石墨烯复合镀层.采用扫描电镜(SEM)、能谱仪(EDS)、X射线光电子能谱仪(XPS)、Raman光谱仪等,对石墨烯片层和Cu基镀层的微观形貌进行表征.利用电化学工作站、纳米压痕仪等对金属镀层的性能进行测试.利用热震法对Cu基镀层与光纤基体的结合性能进行分析,同时对金属镀层光纤进行导光测试.结果发现:Cu-石墨烯镀层相对Cu镀层,镀层组织致密,晶粒细小,质量更优.Cu-石墨烯镀层硬度、弹性模量分别提升了35.3％、34.0％.Cu-石墨烯镀层的腐蚀电位Ecorr提升了32.3％,腐蚀电流icorr减小了22.5％,其耐蚀性能明显提升.石英光纤表面化学镀覆Cu金属镀层,能够克服光纤包层光滤除器在实际应用中因局部温度过高而烧损等问题,同时对光纤的信号光传递并无影响.石墨烯片层对光纤对表面镀层质量、提高防腐等性能影响较大,在提升光纤使用寿命方面具有重要意义.“,”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 spectra 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 35.30％and 34.0％respectively.The corrosion potential Ecorr of Cu-graphene coating is increased by 32.3％,and the corrosion current icon is decreased by 22.5％.The corrosion resistance of Cu-graphene coating 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 filter of optical fiber cladding 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.
