A method for making a conductive polymer for electromagnetic shielding purposes includes steps of mixing liquid crystal monomers, a silver complex, an initiator, and a catalytic agent in certain proportions by weight to form a mixture. A solvent is added into the mixture, the mixture and the solvent being in a ratio from 3:17 to 1:3 by weight. The mixture is heated to undergo an atom transfer radical polymerization.
