中文摘要:
      通过化学镀的方法制得了Ni-P碳纳米管复合粉体,分别在400℃和700℃对所得的样品进行热处理。分析了复合粉体的物相和形貌,测试了复合粉体的电导率和电磁参数,结果表明:高温热处理后镀层由非晶态的Ni-P转化为立方体的Ni和Ni3P;热处理后样品的透射电镜明显可见10~ 50 nm大小的镍颗粒附着在纳米管的表面;复合粉体热处理后的电导率和磁化强度增大,获得了较好的电磁参数。高温退火是进一步提高其电磁性能的有效方法。
英文摘要:
      Ni-P-coated carbon nanotubes particles were prepared using electroless plating method. Composite powder was heat treatment at 400℃ and 700℃ , respectively. The morphology,crystal struck,conductivity and dielectric property of composite powder were investigated.Itis found that the carbon nanotubes powderis successfully coated with Ni-P. After heat treatment, amorphous Ni-P alloy is transitions to single phase Ni and Ni3P which have a face-centred cubic crystal structure. The Ni particles with an average size 10~ 50 nm is found on the surface of the carbon nanotubes. At the same time, conductivity and dielectric property of composite also increase. Heat treatment is an effectively method to optimize the electromagnetic property.
