Stable polyaniline and polypyrrole nanolayers on carbon surface

Eeonomers® are a new class of thermally stable, pH-neutral, and electrically conductive composites made via “in-situ” deposition of polyaniline (PANI) or polypyrrole (PPY) on carbon black (CB). Eeonomers® are more stable (up to 300 °C) than doped intrinsically conductive polymers (ICPʹs) and more easily processable with thermoplastics than CB. The improved thermal stability of doped ICPʹs on CB may be explained by multiple π-π interactions between the unsaturated backbone of the polymer, the aromatic rings of the CB, and the dopant ions. By varying the ICP/CB ratio it is possible to tune Eeonomer® surface properties to achieve low percolation thresholds in the homogeneous and two phase plastic blends.
