摘　　要：在已镀铜涤纶织物表面采用电镀技术制备了一种非晶态Ni-Fe-P合金屏蔽织物。选用8因素3水平的正交试验对制备工艺进行了探讨研究,分析了电镀液组成对镀层沉积速率及组分的影响,借助SEM、EDS和XRD对镀层表面形貌、成分及结构进行了分析,并测试了合金织物的电磁屏蔽效能。结果表明,制备非晶态Ni-Fe-P合金织物的电镀工艺为硫酸镍135 g/L,硫酸亚铁105 g/L,次亚磷酸钠8 g/L,抗坏血酸24 g/L,柠檬酸36 g/L,亚磷酸22 g/L,温度65℃,p H值=1.5,电流密度13 A/dm2,合金织物表面镀层致密均匀,结晶细致,镀层为非晶态结构的Ni-FeP合金,其中P的质量分数为18.67%,在300 k Hz^1.5 GHz频率范围内,合金织物电磁屏蔽效能达到了60.82~73.63 d B。A flexible shielding fabric with dense uniform coating was prepared after electrical deposition of amorphous NiFe-P alloy on copper-coated polyethylene terephthalate( PET) fabric. The manufacturing process was studied using orthogonal test with 8 factors and 3 levels. Analyzed the components of the plating solution on the influence of the disposition rate and composition of coating. The morphology,composition,and structure of coating were analyzed by SEM,EDS and XRD characterizations. The EMI shielding effectiveness was also tested. The results indicate the processing conditions of electrical deposition amorphous Ni-Fe-P alloy coated fabric are: 135 g / L Ni SO4·6H2O,105 g / L Fe SO4·7H2O,8 g / L Na H2PO2·H2O,24 g / L C6H8O6,36 g /L C6H8O7,22 g /L H3PO3,65 ℃,p H = 1. 5,and current density = 13 A / dm2. The results fabric possesses dense,smooth,and uniform coating,which consists of amorphous Ni-FeP alloy with 18. 67wt% P. The EMI shielding effectiveness of this coated fabric achieves 60. 82-73. 63 d B in a broad frequency range between 300 k Hz-1. 5 GHz.
