Title
(EN) GRAPHENE-BASED ELASTIC HEAT SPREADER FILMS
(FR) FILMS DE DISSIPATION THERMIQUE ÉLASTIQUES À BASE DE GRAPHÈNE
Abstract
(EN)
Provided is a elastic heat spreader film (and production process for manufacturing same) 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.
(FR)
L'invention concerne un film de dissipation thermique élastique (et son procédé de production) comprenant : (A) un élastomère ou un caoutchouc en guise de matériau liant ou de matériau de matrice ; et (b) de multiples feuilles de graphène qui sont liées par le matériau liant ou dispersées dans le matériau de matrice, les multiples feuilles de graphène étant sensiblement alignées pour être parallèles les unes aux autres et l'élastomère ou le caoutchouc étant présent à hauteur de 0,001 % à 20 % en poids sur la base du poids total du film de dissipation thermique ; les multiples feuilles de graphène contenant des feuilles de graphène monocouche ou à quelques couches choisies parmi du graphène vierge, de l'oxyde de graphène, de l'oxyde de graphène réduit, du fluorure de graphène, du chlorure de graphène, du bromure de graphène, de l'iodure de graphène, du graphène hydrogéné, du graphène azoté, du graphène dopé, du graphène chimiquement fonctionnalisé, ou leur combinaison ; et le film de dissipation thermique élastique présentant une contrainte élastique de traction entièrement récupérable de 2 % à 100 % et une conductivité thermique dans le plan de 200 W/mK à 1750 W/mK.
