摘要
采用化学镀的方法制备镀铜和镍导电涤纶织物。分别用四探针法和双轴传输线法测量了导电涤纶织物的表面电阻和电磁屏蔽效能。采用扫描电镜(SEM)分析了不同的粗化时间对织物表面粗糙度的影响和化镀铜和镍过程中的表面形态变化。采用自主设计的"透明胶带法"测量金属与织物纤维的结合力。采用条样法测定织物镀金属前后的断裂强力和断裂延伸率。
Conductive Poly（ethylene terephthalate） （PET） fabrics were prepared by electroless copper and nickel plating. The surface resistance and electromagnetic interference （EMI） shielding effectiveness of the conductive fabrics were measured by four point probe method （ASTM F 390） and the coaxial transmission line method （ASTM D4935-99）, respectively. Scanning electric microscope （SEM） analysis was used to observe the morphology of the fabric during the pretreatment and Cu/Ni-P coating growing process. The ＂Scotch tape test＂ was designed to measure the adhesion strength of the metal coating to the PET fabric. The change of breaking strength and elongation of the fabrics before and after metallization was evaluated by strip method according to GB/T 3923.1-1997.
