FLEXIBLE CONDUCTIVE MATERIAL AND TRANSDUCER

摘要

A flexible conductive material of the present invention is formed by dispersing a conductive agent containing carbon nanotubes in a matrix that contains a polymer formed by amide bond formation or imide bond formation of a polycyclic aromatic component and an oligomer component and that has a glass transition point of 20° C. or less. The flexible conductive material of the present invention has good dispersibility of a conductive agent containing carbon nanotubes and has an excellent following performance to an expanding and shrinking substrate. A transducer of the present invention includes a dielectric layer made of a polymer, a plurality of electrodes with the dielectric layer interposed therebetween, and wirings connected to the respective electrodes, and at least either the electrodes or the wirings include the flexible conductive material of the present invention. The transducer of the present invention has a performance that is unlikely to deteriorate due to the electrodes or the wirings and has excellent durability.
