摘 要：<正>Polyaniline-barium titanate （PAn-Ba-TiO3） ultrafine composite particles were prepared by the oxidative polymerization of aniline with H2O2 while barium titanate nanoparticles were synthesized with a sol-gel method. The infrared spectrogram shows that the polymerization of PAn in the hybrid process of PAn-BaTiO3 is similar with the polymeric process of pure aniline, and there is interaction of PAn and BaTiO3 in the PAn-Ba-TiO3. SEM and TEM results show that the average diameter of the composite particles is 1.50/m and the diameters of BaTiO3 nanoparticles are 5—15 nm in the composite particle. The electrical conductivity of the ultrafine composite particles is transformable from 100 to 1011S/cm by equilibrium doping or dedoping method using various concentration of HCl or NaOH solutions.
