NOVELTY - Folding, bending and stretching flexible high heat conducting film comprises 0.5-22.5 wt.% graphene-based materials, 29.5-67.5 wt.% acrylate group, less than or equal to 15 wt.% heat-conducting filling material and 1-8 wt.% film-forming auxiliary agent. USE - The folding, bending and stretching flexible high heat conducting film is useful in chips, hard disks and automotive electronic systems. ADVANTAGE - The folding, bending and stretching flexible high heat conducting film: avoids the foreseeable adverse factor of silicon volatilization; has higher ductility; can be moved up, down, left, right, front, back, etc. without being restricted by directionality thus avoids the obvious disadvantage that carbon fiber heat conduction medium must have orientation to conduct heat better. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing folding, bending and stretching flexible high heat conducting film, comprising (i) adding the graphene-based material first into the acrylate base, and stirring at high speed for 12 minutes to dissolve fully; (ii) adding film-forming auxiliary agent, stirring continuously for 1 minute, adding heat-conducting filling material and stirring at high speed for 15 minutes; and (iii) applying the above slurry on a release paper with a thickness of 4mm, and placing it in a room with a temperature of 20℃ and a humidity of 55% for 6 hours to form a film.
