Abstract: Polyaniline (PANI) and polyaniline/Zr (PANI/Zr) powders have been prepared by in situ polymerization method,and the morphology, structure and pore structure are investigated. Quantum-chemical calculations showed thatthe polyaniline structure formed with zirconium ions is not globular, but fiber-like, and its fiber patterns arecharacterized by clear orientation of individual fragments Estimation of the theoretical and experimental specificsurface area of the PANI/Zr composite is done. It is shown that the most preferred is the fiber-like structure withthe specific surface area about 128-162 m2/g, which stability may be improved by using zirconium (IV)containing substances as a dopant. Experimental specific surface area is 66.8 and 146.05 m2/g for PANI andPANI/Zr, respectively. Correlation between theoretical and experimental specific surface area PANI/Zrcomposite is observed.
