摘要 以钛酸丁酯和金属盐酸盐为原料,采用溶胶一凝胶工艺制备CoFe2O4/TiO2复合薄膜。探讨热处理温度和前驱液pH值对CoFe2O4/TiO2复合薄膜结构及磁性的影响。通过X射线衍射(XRD)分析了复合薄膜的相结构;采用扫描电子显微镜(SEM)、原子力显微镜(AFM)和偏光显微镜(PLM)观测了薄膜表面形貌;用振动样品磁强计(VSM)测试了样品的磁性。结果表明,薄膜生长过程中两相组分的晶体各自析出长大,CoFe2O4均匀地嵌埋于TiO2基体中;薄膜中晶粒的生长对反应体系的pH值、热处理温度依赖性较大,前驱液pH在2-3范围内,经800℃热处理后得到纳米复合薄膜,晶粒平均粒径为19nm;随着热处理温度的升高,复合薄膜的磁性增强。
