通过原位聚合，将聚苯胺接枝到多壁碳纳米管的表面，制备了聚苯胺/碳纳米管纳米纤维。聚苯胺均匀地包覆在碳纳米管表面，当苯胺与碳纳米管投料比为11时，包覆层厚度约为15 nm。聚苯胺/多壁碳纳米管的电导率和塞贝克系数随温度升高而增大，且增大碳纳米管含量同时提高了复合材料的电导率和塞贝克系数，改善了功率因子。

PANi was grafted onto the surface of multi - walled carbon nanotubes ( MWNTs ) by in - situ polymerization. Transmission electron microscopy showed that PANi can be evenly coated on the surface of MWNTs and the layer thickness was about 15 nm when the ratio of aniline and the MWNTs was 11. The testings of thermoelectric properties showed electrical conductivity and seebeck coefficient of PANi/MWNTs both increased with the temperature increased and the increase content of MWNTs. The power factors were both greatly improved.
