摘要:

以PbCl2为介质, 采用无电沉积方法制备了掺钯碳纳米管, 并对其形貌和结构进行了表征. 结果表明, 掺入的钯纳米粒子分布均匀、 粒径均一, 掺杂量与粒径尺寸适中; 所掺入的纳米粒子的成分为0价态的钯, 且掺杂类型为p型. 电接触性能测试结果表明, 掺钯碳纳米管与金电极间的接触电阻得到了明显改善, 阻值平均降幅高达近71.09%.

Abstract:

Multi-walled carbon nanotubes(MWCNTs) were oxidized by mixed acid, and immersed into the electroless deposition solution of palladium. After ultrasonicating, resting, and stirring respectively for 5 or 10 min, palladium-doped MWCNTs were prepared, and their morphology and structure were characte-rized. The results showed that the nanoparticles were uniformly distributed onto the MWCNTs with uniform and moderate particle size and doping amount after 5 min of stirring. At the same time, the composition of the doped nanoparticles was detected as zero-valent palladium and the doping type was p-type. In the electrical contact performance test, the contact resistance between the palladium-doped CNTs and the gold electrode was significantly improved, and the average value of the resistance decreased by nearly 71.09%.

Key words: Multi-walled carbon nanotubes, Doping, Electroless deposition, Palladium nanoparticles, Contact resistance
