▎ 摘　　要

NOVELTY - The elastic heat spreader film comprises an elastomer or rubber as a binder material or a matrix material, and multiple graphene sheets (304) are bonded by binder material or dispersed in matrix material. Multiple graphene sheets are substantially aligned to be parallel to one another and where elastomer or rubber is in an amount from 0.001% to 20% by weight based on the total heat spreader film weight. Multiple graphene sheets contain graphene sheets selected from a pristine graphene material has essentially zero % of non-carbon elements, or a non-pristine graphene material having 0.001% to 25% by weight of non-carbon elements. USE - Graphene based highly elastic heat spreader film for electronic device (smart phones, flat-screen Televisions, tablets, and laptop computers). ADVANTAGE - Elastic heat spreader film reduce the thickness of the layer and improves orientation of the graphene sheets. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electronic device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a heat spreader film.
