Preparation of Inorganic Acid-Doped Conducting Polyaniline/Attapulgite Composites and Its Properties *

The transmiting electric polyaniline(PANI) was synthesized by emulsion polymerization which was carried out by using dodecylbenzene sulfonic acid as emulsifier, hydrochloric acid and dodecylbenzene sulfonic acid as doping agent, ammonium persulfate as initiator. The influences of Attapulgite(ATP)on the conductivity of polyaniline were studied. The experimental results show that, when the ATP is 0.75g, the conductivity of 0.002S/cm. The structure of the conductive composite of PANI/ATP was characterized by Fourier transform infrared (FT-IR), X-ray diffraction(XRD)and thermogravimetric(TG)techniques.
