摘要:

选择合适的SDBS/苯胺/H2O三组分O/W微乳液与苯胺单体共存的两相体系,以单体相为单体源,在O/W三组分微乳液中进行了苯胺聚合,所得聚苯胺粒子大小仅为3nm,分布较均匀,且具有较好的导电性能.

Abstract:

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.
