MATERIAL HAVING HIGH THERMAL CONDUCTIVITY AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2018/135517

A1

Provided are: a material having high thermal conductivity that includes an alumina fiber sheet and a resin, wherein the material having high thermal conductivity includes 20-90% by mass of the alumina fiber sheet; and a method for producing a material having high thermal conductivity, the method including (1) a step for preparing a fiber sheet that includes an alumina source by electrostatic spinning or dry spinning in which a dispersion including an alumina source and a water-soluble polymer is used as a spinning material, (2) a step for firing the fiber sheet including an alumina source to prepare an alumina fiber sheet, and (3) a step for impregnating the alumina fiber sheet with a resin solution having a resin concentration of 10% by mass or less.
