ResearchProgressonGrapheneHeatDissipationFilms
Abstract:
Inrecentyears,withtherapiddevelopmentofmicroelectronicsandoptoelectronicdevices,thedemandforefficientheatdissipationhasbecomeincreasinglyurgent.Traditionalheatdissipationmaterialsandmethodsarefacingchallengesduetotheirlimitationsinthermalconductivityandheatdissipationefficiency.Graphene,atwo-dimensionalcarbonmaterial,hasextraordinarythermalconductivityandexcellentmechanicalproperties,makingitapromisingcandidateforheatdissipationapplications.Thispaperpresentsacomprehensivereviewoftheresearchprogressongrapheneheatdissipationfilms,includingtheirfabricationmethods,performanceevaluation,andpotentialapplications.Thechallengesandfutureprospectsinthisfieldarealsodiscussed.
1.Introduction
Withthecontinuousminiaturizationandintegrationofelectronicdevices,theheatgeneratedduringoperationisbecomingmoreconcentrated,leadingtoelevatedtemperaturesandpotentialdevicefailure.Therefore,efficientheatdissipationhasbecomeacriticalissueinthedesignandperformanceofelectronicdevices.Traditionalheatdissipationmaterials,suchascopperoraluminum,havelimitationsduetotheirlowthermalconductivityandbulkiness.Graphene,atwo-dimensionalcarbonmaterial,hasattractedsignificantattentionduetoitsextraordinarythermalconductivityandmechanicalproperties,makingitapromisingmaterialforheatdissipationapplications.
2.FabricationMethods
Variousmethodshavebeendevelopedtofabricategraphenefilmsforheatdissipation.Chemicalvapordeposition(CVD)iswidelyusedtosynthesizelarge-scalegraphenefilmswithhighqualityandlowdefectdensity.Transfertechniques,suchaspolymer-assistedtransferandthermalreleasetapemethods,areemployedtotransferthegraphenefilmsontodesiredsubstrates.Othermethods,suchaschemicalreductionofgrapheneoxideandepitaxialgrowth,arealsoutilizedtofabricategraphenefilmswithspecificproperties.
3.PerformanceEvaluation
Thethermalconductivityofgraphenehasbeenreportedtobeexceptionallyhigh,upto5000W/mKatroomtemperature.Thismakesgrapheneanidealmaterialforheatdissip
