【摘要】：用Na OH粗化处理芳纶纤维,然后用化学镀方法实现了芳纶纤维表面Ag金属化。使用扫描电子显微镜(SEM)、原子力显微镜(AFM)和X射线光电子能谱仪(XPS)等手段对纤维的表面形貌和元素组成进行了表征,使用X射线衍射仪(XRD)分析了镀银前后纤维的晶体结构变化,使用纤维强伸度仪和热重分析仪(TG)测量了芳纶纤维在镀银前后的力学性能和热稳定性,用万用表测试了镀层的导电性能。结果表明:Ag金属层均匀致密地包裹在纤维的表面,结合牢固度较高。镀银使纤维的热稳定性有所提高,对力学性能的影响较小,电阻达到0.52Ω/cm,在冷热水循环和盐水环境下银层的稳定性较好。
[Abstract]:The aramid fiber was roughened by NaOH, then Ag metallized on the surface of aramid fiber was realized by electroless plating. Scanning electron microscope (SEM) was used. The surface morphology and elemental composition of the fibers were characterized by atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). The crystal structure changes of the fibers before and after silver plating were analyzed by X-ray diffractometer (XRD). The mechanical properties and thermal stability of aramid fiber before and after silver plating were measured by means of tensionometer and thermogravimetric analyzer (TG). The electrical conductivity of the coating was tested by multimeter. The results show that the metal layer of 1: AG is uniformly and compactly wrapped on the surface of the fiber, and the bonding fastness is relatively high, and the thermal stability of the fiber is improved by silver plating. The resistance is 0.52 惟 / cm, and the silver layer is stable in hot and cold water cycle and brine environment.
