Graphene　is　a　two-dimensional　nanomaterial　with　ultra-high　thermal　conductivity，which　is　widely　used　in　the　field　of　electric　heating.　By　analyzing　the　research　progress　of　graphene　and　its　flexible　electrothermal（membrane）materials，the　preparation　methods　of　graphene　of　different　sizes　and　the　effect　of　functional　modification　on　the　thermal　conductivity　of　graphene　are　introduced.　The　applications　of　graphene　flexible　electric　heating（film）materials　in　the　fields　of　deicing　and　anti-fogging，wearable　clothing　and　low-temperature　battery　thermal　management　are　summarized.　In　the　future，it　is　still　necessary　to　break　through　the　technical　problems　of　the　preparation　process　of　graphene　and　its　flexible　heating　（film）　materials　and　the　integration　of　heating　elements.　©　2025　Chinese　Academy　of　Sciences.　All　rights　reserved.
