采用SEM、EDS和XRD测试方法对制备的化学镀银间位芳纶织物纤维表面形貌、镀层成分及物相组成进行分析,探讨了装载量对镀银件导电性的影响,并对镀层进行结合强度、耐腐蚀性和热稳定性测试。结果表明,合适的化学镀银装载量为80 cm~2/L,该条件下制备的镀银层连续致密与基体结合力强,表面方块电阻仅约20~30 m?/sq,导电性优良,并具有良好的耐腐蚀性及热稳定性。 相似文献

Silver plating graphite nanosheet (Ag‐NanoG) prepared by electroless plating method with expanded graphite as starting material is an effective approach to increase thermal conductivity of the filler. Herein, a novel thermal conductive composite was prepared by using Ag‐NanoG as thermal conductive filler and epoxy resin as the polymer matrix. The microstructures of NanoG and Ag‐NanoG were characterized by means of scanning electron microscopy, X‐ray powder diffraction and then the thermal conductivity, impact strength, and thermal stability of the composite were investigated. The results showed that the Ag‐NanoG was successfully obtained and it can be homogeneously dispersed in the epoxy resin. The thermal conductivity of composite increased from 0.328 to 1.847 W/m K with 4 wt% Ag‐NanoG filler content. Moreover, the composite exhibited excellent thermal stability and mechanical property.
