Notes:
A lightweight conducting polymer composite was prepared by the incorporation of conducting polypyrrole in the pores of a host polymer to form a conductive network. The inclusion of polypyrrole in a porous cross-linked polystyrene host polymer, prepared by the concentrated emulsion polymerization method, was carried out by imbibing the host polymer with a pyrrole solution (or oxidant solution), partially drying the saturated host polymer, and imbibing it again with the oxidant solution (or pyrrole solution) for 2 h. The conductivity of the polymer composite is as high as 0.5 S/cm and the shielding effectiveness of the composite reaches 26 dB in the frequency range from 1.0 to 2.0 GHz.
