▎ 摘　　要

NOVELTY - The method involves making graphene oxide solution. Graphene oxide is soaked in water. Ultrasonic stirring is performed to form graphene oxide solution. A natural graphite backing film manufacturing. A single-sided graphene heat dissipation film coil is manufactured. Graphene oxide solution obtained is coated on a front side of the natural graphite coil. The natural graphite coil is continuously dried and reduced with reducing agent to form an upper graphene layer. A single-sided graphene heat dissipation film coil is prepared. Graphene oxide solution is coated on a rear end of the natural graphite layer in an upper graphene layer and the natural graphite layer coils. A lower graphene layer is continuously dried and reduced with a reducing agent to form a lower graphene layer, where thickness of the lower graphene layer is 0.025 mm for preparing a double-sided graphene heat dissipation film roll. USE - Double-sided graphene radiating film manufacturing method for high heat dissipation of various electronic products. ADVANTAGE - The method enables realizing simple, easy operation, and ensuring stable quality and better effect of the product, and enhancing the running speed of the electronic products and the comfort of users, and increasing the service life of the products.
