Abstract��
��his article reported a chemical method to synthesize polyaniline powders with (NH��4)��2S��2O��8 as oxidator in 1M HCl solution.From the nickel��coated carbon fiber felts compounded with epoxy resin and polyaniline the compact composite was obtained.��The article discussed the effects to absorption ability in the presence of Ni��coating carbonfiber felts and polyaniline powders.����
