摘要
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50nm。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。
The crude carbon nanotubes （CNTs） was purified.Nickel plating carbon nanotubes （Ni/CNTs） was prepared by electroless plating method.Then the magnetic pressure sensitive adhesive （Ni/CNTs/PSA）,comprising acrylate resin and Ni/CNTs,was prepared by solution blend method.The SEM and EDS images indicate that a layer of compact nickel homogeneously dispersed on the surface of CNTs and the thickness of nickel layer is about 50 nm.SEM results show that the nickel plating CNTs was homogeneously dispersed in the acrylate pressure sensitive adhesive.The increase of the Ni/CNTs content could enhance the saturation magnetization （Ms） and 180° peel strength of Ni/CNTs/PSA.When the content of Ni/CNTs is 3.0vol％,the magnetic properties and mechanical properties of the Ni/CNTs/PSA composites are optimum.
