Patent ID: 8920620

Claim:
An electrode coating composition comprising: a polymerized product of: from about 5% to about 30% by weight of at least one crosslinkable monomer; from about 20% to about 85% by weight of at least one hydrophobic monomer; and at least one dielectric constant enhancing agent in an amount 2 to 60% by weight selected from the group consisting of: a dielectric enhancing monomer in an amount from about 10% to about 60% by weight, ferroelectric particulates in an amount from about 5% to about 50% by weight, an electroactive polymer in an amount from about 2% to about 20% by weight, and a combination thereof, wherein the coating has a high dielectric constant of from about 1.5 to about 10 and has a high breakdown voltage property of about 1,800 volts per micron, and wherein the dielectric constant enhancing agent comprises a mixture of an electroactive polymer consisting of polyaniline and a dielectric enhancing monomer of furfuryl methacrylate, the mixture is copolymerized with the at least one hydrophobic monomer and the at least one crosslinkable monomer in the coating.
