摘要：

Polyaniline-silver nanocomposites were synthesized in the form of colloidal particles by the facile onestep aqueous chemical oxidative dispersion polymerization of aniline using silver nitrate as an oxidant and poly(vinyl alcohol) as a colloidal stabilizer. Aniline monomer was oxidized by silver ions, yielding polyaniline and elemental Ag simultaneously. The synthesized nanocomposite particles were colloidally stable over 2 years and transmission electron microscopy studies indicated the production of spherical, plate and rod-shaped polyaniline-silver nanocomposite particles with a silver core-polyaniline shell morphology. The conductivity of a pressed pellet of the nanocomposite particles using the conventional four-point probe technique was 1.4 x 10(-2) S/cm at 25 degrees C. The nanocomposite particles behaved as a 'colored' particulate emulsifier for the stabilization of transparent oil-in-water emulsions. (C) 2010 Elsevier B.V. All rights reserved.
