中文摘要:
      采用自制的银活化液对聚酯短切纤维粉进行敏化、活化处理后,以化学镀的方法在该纤维表面镀银,制备具有低电阻率的有机导电纤维粉。研究了化学镀银过程中,纤维粉表面镀银层的形成和变化过程,扫描电镜观察了镀银层的形貌变化,EDAX能谱和X射线衍射(XRD)分析了不同反应时间镀银层的银含量和组成。结果表明:纤维粉镀银后,其镀银层的结构致密,银的平均晶粒尺寸约为0. 452nm,且分布均匀,有金属光泽;镀层中银的质量分数最高为84. 810-/0。对镀银纤维粉的电性能测试表明,一定时间内,该镀银纤维的室温电阻率随着时间的延长而显著降低,其最低室温电阻率为5. 85×10 -4 Ω.cm,该镀银纤维粉显示了优良的导电性。
英文摘要:
      The poly ( PET) fiber powders with low electric resistance were prepared via electroless silver plating after being deal with silver colloid for sensation and activation. Effects of electroless plating times on the change of silvercoated layer and conductivity of the fibers were investigated. The morphologies of the silver coating were observed through the scanning electron microscopy ( SEM) . The contents and crystalline of the coated silver were determined by energy disperse X-ray analysis ( EDAX) and XRD. The results show that the silver coating of PET fibers is dense and uniform, and exhibites silver color. The silver content of the coating layer is 84. 810-/o and the average crystallite size is 0. 45185nm. The volume electric resistance rate of the silver-coated fiber reaches 5. 85 x 10-4 Ω.cm. The prepared conductive PET fiber powder shows high conductive compared with original fibers.
