| 摘 要： | 用化学镀法,甲醛为还原剂,制备镀银羰基铁粉.用XRD,SEM和EDX对粉体进行表征.用重法测定粉体的抗氧化性能,并以镀银羰基铁粉制备电磁屏蔽材料,检测其在100kHz～1.5GHz的屏蔽效能.结果表明:用该法制备的镀银羰基铁粉能够实现表面银层包覆完整、致密;羰基铁粉镀银后的抗氧化性能得到明显提高;电磁屏蔽材料在100kHz～1.5GHz频率范围内获得优于-32dB的屏蔽效能.

| Abstract: | Silver-coated carbonyl iron powder was prepared by using electroless plating metnoo, formaldehyde was used as reducer. The powder was characterized by XRD, SEM and EDX. Anti-oxidation was tested by TG. And SE of electromagnetic shielding material prepared with silver-coated carbonyl iron powders was investigated at the frequency range of 100kHz-1.5GHz. The results show that this method can prepare the integrative compact silver coating for silver-coated carbonyl iron powders. Oxidation resistance of carbonyl iron powders after being coated with silver was improved obviously. The SE of the electromagnetic shielding material is better than -32dB in the frequency range of 100kHz- 1.5GHz. |
