摘　　要：以化学镀的方法在单壁碳纳米管表面沉积了镍钴磷合金。讨论了Co2+与Ni2+的浓度比、镀液温度、pH对沉积速率的影响。当镀液中Co2+与Ni2+的浓度比为1时,沉积速率最大。pH和温度的升高都会使沉积速率增大。采用场发射扫描电镜(FE-SEM)、透射电镜(TEM)、X射线衍射(XRD)和能谱(EDS)对制备的碳纳米管复合材料进行表征。结果表明:热处理会使碳管上的非晶镍钴磷合金镀层转变为晶态,从而提高镀层性能。A Ni-Co-P alloy was prepared on the surface of single-wall carbon nanotube by electroless plating. The effects of the concentration ratio of Co^2＋ to Ni^2＋, bath temperature and pH on deposition rate were discussed. The deposition rate reached a maximum when the concentration ratio of Co^2＋ to Ni^2＋ is 1. The increase ofpH and temperature increases the deposition rate. The carbon nanotube composite was characterized by field-emission scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, X-ray diffraction （XRD） and energy dispersive spectroscopy （EDS） The results showed that the heat treatment induces a transition of Ni-Co-P alloy deposit on carbon nanotube from amorphous to crystalline, resulting in an improvement of deposit properties.
