Authors have investigated the thermal and electrical conduction behavior of Al/MWCNT composite fabricated by powder metallurgy method in which CNTs were pre-encapsulated with Ni. The thermal and electrical conductivity values were found proportional to the addition of CNTs. For 2.5% wt. CNTs addition with HIP treatment, the Al/CNT composite showed thermal conductivity of 476 W/m-k which is about 85% higher than the value of pure Al. Also, the resultant electrical conductivity was 0.405 × 10⁻⁸ S which is about 14% higher than the value of pure Al. The increased thermal and electrical conductivity can be attributed mainly to the well dispersion of CNTs through Ni-encapsulation and the enhanced interfacial bonding of Ni-coated CNTs with the matrix. Due to having good electrical conductivity of nickel itself, electrical conductivity of the composite was also enhanced which was further confirmed from First Principle study.

作者研究了通过粉末冶金方法制造的铝/多壁碳纳米管复合材料的导热和导电行为，其中碳纳米管用镍预封装。发现热导率和电导率值与碳纳米管的添加量成正比。对于 2.5% wt。通过 HIP 处理添加 CNT，Al/CNT 复合材料的热导率为 476 W/mk，比纯铝的值高约 85%。另外，所得的电导率为0.405×10 ^-8S 比纯 Al 值高约 14%。增加的热导率和电导率主要归因于通过 Ni 封装的 CNT 的良好分散以及 Ni 包覆的 CNT 与基体的增强界面结合。由于镍本身具有良好的导电性，复合材料的导电性也得到了提高，这从第一性原理研究中得到了进一步证实。
