Spherical Polyelectrolyte Brushes as Templates for Stable Dispersions of Polyaniline Based Conducting Particles

Authors


Abstract

We prepare stable conducting core-shell particles using spherical polyelectrolyte brushes (SPB) as microreactor-templates. The polymerization of aniline is guided within the SPB shell so that no bulk polymerization proceeds up to 20% polyaniline (PANi) content in the resulting composite. The dispersions are electrostatically stabilized in a wide range of the ionic strength. The conductivity of the composite material reaches 0.1 S/cm which is comparable with the conductivity of bulk PANI obtained under comparable conditions.
