Abstract
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.
Claims7
A method for making a conductive polymer comprising:
- mixing liquid crystal monomers, a silver complex, an initiator, and a catalytic agent to form a mixture, the liquid crystal monomers having a mass percentage of about 42.2% to about 52.2% of a total mass of the mixture, the silver complex having a mass percentage of about 43.1% to about 53.1% of the total mass of the mixture, the initiator having a mass percentage of about 0.85% to about 1.35% of the total mass of the mixture, and the catalytic agent having a mass percentage of about 2.85% to about 4.35% of the total mass of the mixture;
- adding a solvent into the mixture, the mixture and the solvent being in a ratio from 3:17 to 1:3 by weight;
- and
- heating the mixture to undergo atom transfer radical polymerization.
