摘要
利用金属离子在高分子配合物中独特的离子簇结构，通过化学还原和氧化的方法得到了超微氧化铁颗粒。高分子介质对所制备的金属氧化物颗粒有良好的保护和分散作用，有效地防止了超微粒子间的聚集。所得到的高分子金属复合体既具有超细微粒的性能同时又具有高分子材料易加工成型的特点。
A series of matrixmediated nanocomposite was achieved in poly(4vinylpyridine) or itaconic acidacrylic acid copolymers. NH2-NH2 was used as reducing agent to prepare the polymersupported metallic particles which were later converted into fine oxide powders by oxidation. The structure and morphology of the products were studied by FTIR, WAXD and TEM. It was found that the iron particles in polymer matrix were in amorphous state while the oxide particles were in crystalline state PIAAFeO.
