铁/聚氯乙烯高能球磨的穆斯堡尔谱研究

Mssbauer study of iron/polyvinylchloride nanocomposites prepared by high energy ball milling

用高能球磨法制备了铁 /聚氯乙烯 (PVC)纳米复合材料。穆斯堡尔谱学 (MS)用来测量复合材料中铁化合物的组分和铁的价态 ,结果表明复合材料中存在二价铁 (FeCl2 ·H2 O)、三价铁 。

Iron/polyvinylchloride(PVC)nanocomposites were prepared by high energy ball milling technique,Mssbauer spectroscopy(MS)was used to investigate the new components and the change of iron valance.The result shows that Mssbauer spectra can be fitted into four subspectra,two doublets corresponding to Fe +2 (FeCl 2·H 2O)and Fe +3 ,respectively,and two sextets corresponding to bulk and interfacial α Fe.
