ABSTRACT:
The invention relates to the homogenization of mixtures of internally conductive polymers like 3-substituted polythiophene and matrix polymers. With an efficient homogenization the conductivity is improved when the portion of the conductive polymer is low. An efficient homogenization is achieved in the invention by mixing the internally conductive polymer with a monomer or by dissolving it into it, after which the monomer is polymerized. The plastic composites so obtained are used for several purposes in which conductivity is needed, such as EMI and ESD shielding.
