An elastic conductive material includes a matrix and a conductor dispersed in the matrix. The matrix is formed by crosslinking a first polymer that is one or more selected from polymers of General Formulae (1) to (4) below and has a function of dispersing the conductor, and a second polymer crosslinkable with the first polymer.[In Formulae (1) to (4), X is a substituent crosslinkable with the second polymer; Y is a functional group having an affinity for the conductor; constitutional units A, B, and C each are one kind selected from acrylic acid, methacrylic acid, salts of acrylic acid and methacrylic acid, esters, polybutadiene, polyisoprene, urethane prepolymer, polyether, polyetheramine, polyamine, polyol, and polythiol; and l, m, and n each are an integer equal to or greater than one.]

Provided is a conductive film having a high conductivity in which electric resistance is less likely to increase, and a conductive composition for forming the same. The conductive composition includes an elastomer component, a fibrous carbon material having a fiber diameter of less than 30 nm, and a flake-like carbon material having a graphite structure, having an intensity ratio (G/D ratio) of a peak (G band) appearing in the vicinity of 1580 cm−1 to a peak (D band) appearing in the vicinity of 1330 cm−1 of Raman spectrum of not less than 1.8, and having a maximum length of not less than 150 nm and a thickness of not more than 100 nm. The conductive film is formed from the conductive composition.
摘要:
A flexible conductive material of the present invention includes an elastomer and a conductive material including silver at least in a surface. The conductive material is chemically bonded to the elastomer directly or indirectly and is thus incorporated into a mesh structure of the elastomer. Volume resistivity is 1×10−2 Ω·cm or less in a state where the flexible conductive material is expanded by 10% in one axis direction. The flexible conductive material of the present invention is flexible and expandable/contractable and hardly increases in electrical resistance even after repeated expansion and contraction. A method of manufacturing the flexible conductive material of the present invention includes preparing a rubber composition including a rubber polymer composed of the elastomer component, the conductive material, and a reactive compound capable of being chemically bonded to both the elastomer and the conductive material and mixed when necessary; and cross-linking the prepared rubber composition.
