Studies on monodisperse core/shell conductive polymer composite materials (I) - Characterization of monodisperse core/shell polystyrene/polypyrrole structure
by Yang, Z. L.; Hou, W. B.; Liu, Z. P.; Huang, L. Y.; Peng, X. G.
Monodisperse core/shell latex particles composed of a polystyrene (PS) core and a thin conductive polypyrrole (PPy) shell were synthesized by means of two-stage emulsion polymerization. Proofs for the success of core/shell synthesis were obtained by using transmission electron microscopy (TEM) and Xray photoelectron spectroscopy (XPS). Pressed pellet conductivity measurements on the dried composites indicated a low percolation threshold of 13.8%. The conductivity for the composites was higher than that of a heterogeneous admixture of dried PS latex and PPy bulk powder. The highest conductivity of the core/shell composite was 0.14 S/cm.
