Preparation and Electromagnetic Properties of Ni-Coated Multi-Wall Carbon Nanotubes
摘要
Abstract
After purification, sensitization, activation of multi-wall carbon nanotubes ( CNTs ) , Ni-coated CNTs were produced by electroless plating. By DSC analysis, suitable heat treatment temperature is excavated, then Ni-coated CNTs were annealed under inert gas atmosphere. The products were characterized by transmission electron microscopy (TEM) ,energy chromatog raphy (EDS) ,X-ray diffraction (XRD). The results show that CNTs surface is successfully coated with a layer of nickel-phosphorus alloys, and Ni-coated CNTs after heat treatment is smoother and crystallization reaction is occurred, thereby electromagnetic performance is greatly enhanced. The test of electrical properties show that the conductivity of Ni-coated CNTs is 450 S/m, and is improved to 1 400 S/m after the heat treatment. The test of magnetic properties show Ni-coated CNTs before and after the heat treatment are soft magnetic material, the saturation magnetization is 2. 753 emu/g before the heat treatment,and is improved to 11. 254 emu/g after the heat treatment.关键词
