摘要
采用化学镀方法在聚酯布表面沉积1层Ni-P合金,用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、热重分析仪(TG)对镀层形貌、结构和性能进行表征。结果表明:聚酯布表面化学镀Ni-P合金由大小为0.1～1μm的微粒组成;镀层为非晶结构、热稳定性好、与聚酯布之间的结合力好;表面化学镀Ni-P合金后的聚酯布对频率<20GHz的电磁波屏蔽效能可达到60dB,具有较好的电磁屏蔽效果。
Ni-P alloy coating was covered on surface of poly（ethylene terephthalate） （PET） fabric by electroless plating technology. Morphology,structure and property of the Ni-P plating were characterized by scanning electron microscopy （SEM）,X-ray diffraction （XRD）,thermogrametric analysis （TG） and infrared spectrometer （IR）,respectively. The results showed that the Ni-P alloy coating on surface of PET fabric,which was composed of 0.1-1μm grains,was non-crystal and owned good stability of thermodynamics. There was good adhesion between Ni-P plating and PET fabric. Compared with those before plating,the intensity of IR of PET fabric after plating were decreased. The shielding effectiveness （SE） to frequency less than 20GHz of Ni-P -coated fabric was above 60dB.
