【摘要】 运用穆斯堡尔谱、TEM、XRD方法研究了Fe3O4／聚氯乙烯（PVC）粉末高能球磨产物，发现有超顺磁性α-Fe2O3生成，其形成原因可能是聚合物在空气中降解,生成含氧官能团与Fe3O4相互作用.更多还原

【Abstract】 The high energy ball milling products for a mixture of Fe3O4 and polyvinyl chloride(PVC) powders were investigated by using 57Fe Mossbauer spectroscopy, TEM and XRD. It was suggested that the formation of superparamagnetic α-Fe2O3, could be ascribed to the polymer degradedin air and interaction between oxygen-containing radicals and Fe3O4.更多还原
