Composite material and mixture

Abstract

A composite material includes: a dispersion having a thermal conductivity of 100 W / m·K or higher, and a thermoplastic resin matrix having a volume resistivity of 10 GΩ·cm or higher, situated between the dispersions. A mixture includes: a dispersion having a thermal conductivity of 100 W / m·K or higher and a particle size distribution having one or more maxima, and a powder having a volume resistivity of 10 GΩ·cm or higher, wherein the volume ratio of the powder to the total volume of the dispersion and the powder is 0.5 vol% or more and 50 vol% or less. The composite material includes: a dispersed material having a thermal conductivity of 100 W / m·K or more; and a thermoplastic resin matrix having a volume resistivity of 10 GΩ·cm or more and interposed between the dispersed materials. The ratio of the powder to the total volume of the dispersed material and the powder is 0.5 vol% or more and 50 vol% or less.
