摘　　要：采用水热法和化学共沉淀法分两步合成了ZnO/CoFe2O4复合体.吸波性能测试结果表明,ZnO/CoFe2O4复合体吸波性能有所提高.这主要归因于CoFe2O4和ZnO的复合,实现了阻抗匹配,充分利用了CoFe2O4铁氧体的磁损耗和ZnO材料的介电损耗,从而获得性能优越的吸波剂材料.ZnO/CoFe2 04 composites were prepared in two steps by using hydrotherrnal and chemical precipitation method. The electromagnetic measurements showed that the microwave absorbing properties of ZnO/CoFe2 04 corn-
