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α -Fe六线峰之上
High-energy ball milling prepared iron / PTFE nanocomposites, the morphology and structure of high-resolution transmission electron microscopy and Mossbauer spectroscopy methods, high-resolution transmission electron micrographs show iron particles around the existence of non-crystalline boundary , The average particle size of iron particles is about 8nm. Mossbauer spectroscopy results show that there are two ferrous iron and interface spectrum superimposed on the original α-Fe six-line peak
