Abstract
Provided is a elastic heat spreader film comprising: (a) an elastomer or rubber as a binder material or a matrix material; and (b) multiple graphene sheets that are bonded by the binder material or dispersed in the matrix material, wherein the multiple graphene sheets are substantially aligned to be parallel to one another and wherein the elastomer or rubber is in an amount from 0.001% to 20% by weight based on the total heat spreader film weight; wherein the multiple graphene sheets contain single-layer or few-layer graphene sheets selected from pristine graphene, graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene, chemically functionalized graphene, or a combination thereof; and wherein the elastic heat spreader film has a fully recoverable tensile elastic strain from 2% to 100% and an in-plane thermal conductivity from 200 W/mK to 1,750 W/mK.
