摘要 以resol型酚醛树脂为前驱体,F127为模板剂,采用简单的一步法制备了磁性有序介孔碳材料,并对所得材料进行X射线衍射、N2吸附脱附、透射电子显微镜(TEM)、磁性能表征。在较低的Co含量下,所得材料保持了良好的二维六方有序结构(p6mm),随着Co含量的增加,介孔材料的有序性逐渐降低。所得样品中磁性粒子是以Co单质的形式存在的,且少量磁性前驱体的加入能够提高介孔复合材料的比表面和孔容,但是前驱体的持续增加会导致所得材料比表面和孔容的降低。所得材料在室温下表现出软铁磁性,饱和磁化强度等磁性能参数可以通过Co含量的改变而改变。 以resol型酚醛树脂为前驱体,F127为模板剂,采用简单的一步法制备了磁性有序介孔碳材料,并对所得材料进行X射线衍射、N2吸附脱附、透射电子显微镜(TEM)、磁性能表征。在较低的Co含量下,所得材料保持了良好的二维六方有序结构(p6mm),随着Co含量的增加,介孔材料的有序性逐渐降低。所得样品中磁性粒子是以Co单质的形式存在的,且少量磁性前驱体的加入能够提高介孔复合材料的比表面和孔容,但是前驱体的持续增加会导致所得材料比表面和孔容的降低。所得材料在室温下表现出软铁磁性,饱和磁化强度等磁性能参数可以通过Co含量的改变而改变。
