在已化学镀铜涤纶织物上电沉积非晶态Ni-Fe-P和 Ni-P 合金,制备了镀层致密均匀的柔性金属化屏蔽织物.讨论了电流密度、温度及 pH 值对镀层组成和沉积速率的影响,借助SEM、EDS和XRD测试仪器对镀层表面形貌、成分及结构进行了分析,并测试了镀层织物电磁屏蔽效能.结果表明,当电流密度为8．7 A/dm2,温度为60℃,pH 值＝1．5时,非晶态 Ni-Fe-P合金的织物镀层结晶细致,致密均匀,镀层为 P含量为16．62％的非晶态结构.通过对比分析,非晶态Ni-Fe-P合金织物的电磁屏蔽效能较好.在300 kHz~1．5 GHz频率范围内,镀层织物电磁屏蔽效能达到了69．20~80．30 dB.

A flexible shielding fabric with dense uniform coating was prepared after electrical deposition of amor-phous Ni-Fe-P and Ni-P alloy on copper-coated polyethylene terephthalate (PET)fabric.The effects of coating composition and the deposition rate were discussed by the current density,temperature and pH value.The mor-phology,composition,and structure of coating were analyzed by SEM,EDS,and XRD characterizations.The EMI shielding effectiveness and corrosion resistance were also tested.The results fabric possesses dense, smooth,and uniform coating,when the processing conditions are 60 ℃,pH=1.5,and current density=8.7 A/dm2 .The coating fabric consists of amorphous Ni-Fe-P alloy with 16.62% P (weight percent),which has excellent of corrosion resistance.By contrast the EMI shielding effectiveness of amorphous Ni-Fe-P was better than amorphous Ni-P.The EMI shielding effectiveness of this coated fabric achieves 69.20-80.30 dB in a broad frequency range between 300 kHz-1.5 GHz.
