摘　　要：Polyaniline/fractionized carbon nanotube composite was prepared with the polymerization of aniline in the FCNTs dispersed liquid. The SEM micrographs indicate that carbon nanotubes are coated with polyaniline; the thickness of the polyaniline on carbon nanotubes is about 5～10 nm; and carbon nanotubes were dispersed well in the composite on the nanometer scale. The apparent density and the electrical conductivity of the polyaniline/fractionized carbon nanotube composite are 440 kg/m+3 and 173 S/m, respectively. As compared with polyaniline, the apparent density and the conductivity of the composite increased by about 82% and 1400%, respectively. TGA tests indicate that the composite has better thermal-stability than that of polyaniline.Polyaniline/fractionized carbon nanotube composite was prepared with the polymerization of aniline in the FCNTs dispersed liquid.
