导电聚合物材料镀层电阻特性及附着力研究

Research of the Resistance Characteristic and Adhesion of the Conducting Polymers Materials Coating

采用磁控溅射和电镀工艺制备了导电聚合物材料,研究了织物的不同编织结构、纤维粗细及工艺等因素对其电阻及附着力的影响。以数字式微欧计测试样品的表面电阻,以强力胶带测试样品的剥离强度,结果表明:织物纤维越细、纤维间排列越松散,表面电阻就越均匀,其抗电磁干扰(EMI)的能力也就越强,其中以无纺布表现最佳。减少镀液中的杂质及镀液结晶有利于提高镀层与基材的附着力,织物编织越密则附着力越差。

Effectiveness and adhesion of the coating and substrate are important prerequisite to achieving its other performances. In the production of conductive polymer materials, non-uniform coating resistance and poor adhesion of the substrate are frequently occurred problems. The magnetron sputtering and plating process were used to prepare the conductive polymer materials, and then the effect of different factors such as woven structure, fiber thickness and process on the coating resistance and adhesion was studied. Use digital microhmmeter to test the sample surface resistance and powerful belt to test the sample peel strength. The results show that： The finer and looser of the weaving fibers, the uniformer of the surface resistance, and the stronger of its anti-EMI ability, especially with the non-woven fabric. Reduction of the impurities and crystallization of the plating solution can improve the adhesion of the coating and substrate. The tighter of the fabric, the poorer of the adhesion. The study can supply feasible technical reference to obtain the conductive polymer materials which have uniform resistance and good adhesion.
