Abstract
A laminate is disclosed that includes a heat-dispersing layer comprising at least 90% by weight of a metal having a melting point of at least 1,300° C., and a thermal conductivity of at least 15 W/Km, or graphite, a first heat-insulating layer comprising at least 90% by weight of a porous polyimide aerogel having a thermal conductivity of 0.03 W/m K to 0.5 W/m K and pores having an average pore diameter of at least 150 nm, a first adhesive layer attached to the heat-dispersing layer and the heat-insulating layer; and a second adhesive layer attached to the heat-insulating layer.
Claims25
A laminate comprising:
