摘　　要：高能球磨法制备了铁 /聚四氟乙烯纳米复合材料 ,其形貌与结构采用高分辨透射电镜与穆斯堡尔谱方法进行研究 ,高分辨透射电镜照片显示铁颗粒周围有非晶状边界存在 ,铁粒子的平均粒径约为 8nm。穆斯堡尔谱结果表明有二价铁以及界面谱叠加在原有的αFe/PTFE nanometer composite was prepared by high energy ball milling,the micrograph and structure was investigated by high resolution TEM and[KG-2] 57 Fe Mssbauer spectroscopy.The micrograph of the high resolution TEM shows that the nanometer composite consists of small crystallites with diameter about 8nm separated by grain boundaries of amorphous phase.And the Mssbauer effect studies show that the spectrum can be fitted to three components,one doublet for Fe 2+ ,and two sextets for bulk and interfacial α Fe.
