Fine particles of polyaniline were prepared in (An+O/W microemulsion) two phase system in which the An phase was used as a monomer source and the O/W microemulsion phase for polymerization. The particle size of polyaniline was less than 10nm and the particles were spherical and well distributed. The measurements of conductivity of polyaniline in DMF showed that polyaniline prepared in microemulsion system had good conductivity. And the measurements of light spectrum of Polyaniline in organic solvents showed λmax=580 nm which was similar to that given in the reference.

Key words: O/W microemulsion, Polymerization of aniline, Polyaniline, Fine particles
