摘要

采用纳米颗粒化学复合镀技术,实现锦纶织物纳米Fe3O4颗粒复合镀铜.借助SEM、EDX、XRD及TG,研究镀层表面形貌、成份和结构以及织物热性能,测试镀铜织物的电磁波屏蔽、表面比电阻和耐磨性能.实验结果表明,较普通镀铜织物,纳米Fe3O4复合镀铜层表面粗糙度有所增加,镀层晶格结构没有改变,但晶粒尺寸有所减小,热性能变化不明显,耐磨性稍有增强.当增重率相同时,纳米Fe3O4复合镀铜织物电磁波屏蔽性能较普通镀铜织物有所降低;随着增重率的增加,平均屏蔽效能逐渐增大,表面比电阻逐渐减小.%In order to study the effect of nano Fe3O4 particle on the properties of Cu-plated fabric, electroless composite coating of Cu-Fe3O4nano particles on polyamide fabric was fabricated in the laboratory. The Cu-Fe3O4-coated fabric was investigated by means of SEM, EDX, XRD and TG. The electromagnetic shielding performance, surface specific resistance and abrasion resistance were also measured. The results show that as compared with the Cu-coated fabric, the surface roughness of the Cu-Fe3O4-coated fabric become coarse. The crystal lattice structure of Cu coating does not change but the grain size decreases. The incorporation of nano Fe3O4 particle has a Iittle effect on the thermal property of Cu-plated fabric. The abrasion resistance of Cu-Fe3O4-coated fabric is improved. When the weight increasing rates are identical, the shielding effectiveness of the Cu-Fe3O4-coated fabric is lower than that of the Cu-coated one. The shielding effectiveness increases but the surface specific resistance decreases with the increase of the weight increasing rate.
