摘　　要：提出了化学镀法制备以光纤包层为基底的钯薄膜材料。经过反复多次试验,优化了化学镀钯的试验方案,在镀膜前对光纤包层进行清洗,预先进行敏化活化(S&A)能够增强非金属基底材料与钯薄膜的附着力,增强机械强度。采用光学显微镜(OM)、扫描电镜(SEM)和能谱仪(EDS)对薄膜的物相结构、表面形貌、元素组成与含量进行了详细的表征和分析,结果显示:薄膜表面呈花菜状,增大了薄膜的表面积,加快了吸收氢气的速率;EDS分析所镀钯薄膜钯元素含量约76%~99%,镀膜效果较好。A chemical plating method was proposed to prepare palladium thin film materials based on fiber cladding.After repeated experiments,the experimental plan for chemical palladium plating was optimized.Before coating,the fiber cladding was cleaned,and sensitization activation(S&A)was carried out in advance to enhance the adhesion between non-metallic substrate materials and palladium films and enhance mechanical strength.The phase structure,surface morphology,elemental composition and content of the film were characterized and analyzed in detail using optical microscopy(OM),scanning electron microscopy(SEM),and energy dispersive spectroscopy(EDS).The results showed that the surface of the film was cauliflower like,increasing the surface area of the film and accelerating the rate of hydrogen absorption.EDS analysis showed that the palladium element content of the palladium plated film was about 76%~99%,and the coating effect was good.
