Structure and Properties of Conjugated Polymer Composites

The structure and properties of electrically conductive composites of conjugated polymers and nonconductive polymers are reviewed in this paper. Conjugated polymers such as polyaniline (PANI) and polypyrrole (PPY) have bad miscibility with common nonconductive polymers, especially nonpolar polymer.But the miscibility can be enhanced greatly by selective doping, chemical graft and introduction of ion bonding and hydrogen bonding, to improve the interaction between conjugated polymers and matrix. Thus some composites were blended to a nanometric or molecular level, and excellent properties happend to those systems, such as very low percolation throsheld, good conductivity, little loss of mechanical properties.
