[Abstract]:A new method for preparation of highly soluble conductive Polyaniline (PANI) was reported. Poly (2-acrylamide) -2-methylpropanesulfonic acid (PAMPS) was used as dopant acid and emulsifier to make use of its unique long chain, hydrophilic and strong acidic group effects. Conductive Polyaniline with high solubility was synthesized by emulsion polymerization. The structure and properties of the products were characterized by (NMR), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The results show that the mass fraction of amps in m (aniline): m (AMPS): m (APS) = 1: 2: 1.5) is 20 and the mass fraction of amps is 30. The reaction time is 5 hours. At the reaction temperature of 5 鈩，
