摘要:
A conductive material according to the present invention includes a polymer having a glass transition temperature (Tg) of 25°C or below and a metal filler containing metal nanowires; and a structure in which wire bundle portions each formed by assembling the metal nanowires are dispersed in the polymer. The conductive material according to the present invention includes the wire bundle portions, in each of which the metal nanowires are assembled. Accordingly, the conductive material is highly extensible, and electrical resistance is not easily increased upon extension. A transducer according to the present invention includes a dielectric layer made of an elastomer, a plurality of electrodes with the dielectric layer interposed therebetween, and wirings each connecting to corresponding one of the electrodes. Either one or both of the electrodes and the wirings are formed of the conductive material.

A load sensor (1) according to the present invention includes: a stretchable and contractible sensor portion (10) for detecting a load, and a wiring portion (01y to 08y) connected to the sensor portion (10). The wiring portion (01y to 08y) includes: a first conductive layer (32) placed on a surface of a substrate (31) with the ability to stretch and contract and containing an elastomer and conductive carbon powder; and a second conductive layer (33) stacked on the first conductive layer (32), having an area smaller than that of the first conductive layer (32), and containing an elastomer and metal powder.

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.

An elastic conductive material includes a matrix and a conductor dispersed in the matrix. The matrix is formed by crossliking 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 1, m, and n each are an integer equal to or greater than one.]
