聚吡咯-钴锌铁氧体复合材料的制备及性能*
Keywords: 复合材料,聚吡咯-co0.5zn0.5fe2o4,磁性能,反射损耗
Abstract:
？用聚丙烯酰胺凝胶法制备纳米co0.5zn0.5fe2o4铁氧体,再用原位聚合法制备聚吡咯-钴锌铁氧体(ppy-co0.5zn0.5fe2o4)复合材料。使用x射线衍射仪(xrd)和扫描电子显微镜(sem)表征了复合材料的结构和形貌,用振动样品磁强计(vsm)和矢量网络分析仪测试了复合材料的磁性能和介电性能。结果表明:样品为纯ppy和ppy-co0.5zn0.5fe2o4,平均粒径分别约为200nm和180nm;co0.5zn0.5fe2o4的磁化强度(ms)和剩余磁化强度(mr)分别为65.95emu/g和15.44emu/g,均大于ppy-co0.5zn0.5fe2o4,但矫顽力(hc)为153.51oe,小于ppy-co0.5zn0.5fe2o4;ppy的介电损耗(tanε=ε''/ε')大于ppy-co0.5zn0.5fe2o4,反射损耗小于ppy-co0.5zn0.5fe2o4,这是co0.5zn0.5fe2o4的引入所致;在频率为15.2ghz处,ppy-co0.5zn0.5fe2o4复合材料的反射损耗达到最大值-16.4db,频带宽为2.5ghz。
