首先对原始碳纳米管(CNTs)进行了纯化处理,再采用化学镀的方法制备了镀镍碳纳米管(Ni/CNTs),并采用溶液共混法制备镀镍碳纳米管/聚丙烯酸酯磁性压敏胶(Ni/CNTs/PSA).扫描电镜(SEM)及X射线能谱仪(EDS)显示CNTs表面镀上了一层均匀紧凑的金属镍,镍层厚度约为50 nm.SEM显示Ni/CNTs均匀地分散在聚丙烯酸酯(PSA)中.Ni/CNTs/PSA的饱和磁化强度(Ms)随着Ni/CNTs含量的增加而增大,Ni/CNTs/PSA的180°剥离强度随着Ni/CNTs含量的增加逐渐下降,剪切强度先上升后下降.当Ni/CNTs的含量为3.0％(体积分数)时,磁性压敏胶综合性能最佳.
