The results show that the compound conductive fiber has typical structure of sheath-core consists of black greened polyaniline electric conductive deposition as the skin and the white polypropylene matrix fiber as the core, which makes the compound fiber preferable physical mechanical property. The intensity and the elongation ratio of the electric conductive fiber are decreased but the thermal stability is enhanced after modified. The compound fiber has the good acid resistance but poor base resistance. The thermal stability of the compound fiber prepared by 4-methyl-benzene sulfonic acid is better than that prepared by hydrochloride acid.
