Abstract:

Conductive polymer microcapsules have become a new research highlight because of its properties of both conductivity and micro/nano structure. Polypyrrole microcapsules containing ZnCl2 solution were chemically synthesized by in-situ polymerization method with water-in-oil emulsion as soft template, sodium dodecylbenzenesulfonate(DBSNa) and p-toluene sulphonic acid(TsOH) as dopants, benzoyl peroxide(BPO) as oxidant. Characterization results show that the polypyrrole microcapcules are regular core-shell structure when the concentration of ZnCl2 is 20%(mass fraction), the mass fractions of DBSNa, TsOH, BPO to the monomer are 1.27%, 4.12%, 123.71%, respectively. And the microcapcules have a fullness and smooth surface and the particle size of about 50 μm. This study is expected to expand the application of water-soluble drugs and all-solid-state ion selective electrode.
