Abstract
The invention relates to a preparation method of nano-polyaniline. The preparation method comprises the following steps of: (1) taking hydrochloric acid or sulfuric acid and performing reaction with aniline to generate an aniline hydrochloride aqueous liquor or an sulfate sulfate aqueous liquor; (2) cooling the aniline hydrochloride aqueous liquor or the sulfate sulfate aqueous liquor to room temperature and atomizing; (3) mixing the atomized the aniline hydrochloride aqueous liquor or the sulfate sulfate aqueous liquor with chlorine dioxide gas and performing reaction of aniline hydrochloride or sulfate sulfate in atomized particles with chlorine dioxide to generate polyaniline; and (4) drying the polyaniline obtained the in the step (3) to obtain polyaniline particles. The method for preparing polyaniline provided by the invention is simple and convenient, and polyaniline is higher in purity with lesser chemical materials. Meanwhile, the polyaniline prepared is used as an antistatic agent, and the conductivity is 0.1-10S/cm. In the depositing process, attenuation of conductivity does not occur, and the nano-polyaniline is further good in compatibility with plastic.
