▎ 摘 要
NOVELTY - Preparation of graphene uniform temperature plate involves: coating and drying graphene oxide slurry, which does not contain binder to obtain a graphene oxide film; stacking several sheets of graphene oxide films to obtain a graphene oxide layer; separating several layers of graphene oxide layers at intervals by using a partition to obtain a stack component with a height set to (H); arranging a stopper above the stack component, where the distance between the lower surface of the stopper and the upper surface of the stack component is 0.5-1.5 H; subjecting the stack component to heat treatment and graphitization to convert the graphene oxide layer into a graphene layer; and calendering. USE - The method is useful for preparing graphene uniform temperature plate used in radiating device and electronic device (all claimed). ADVANTAGE - The method: obtains ultra-thick graphene uniform temperature plate, which has highly directionally arranged graphene, and excellent planar thermal conductivity, and can replace partial functions of heat pipes; solves the technical problem that interlayer bonding force between ultra-thick graphene heat conducting film/plate is insufficient and difficult to manufacture; is simple and cost-effective; and reduces the weight of the radiating component. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the graphene uniform temperature plate, which has a planar thermal conductivity of 800-1400 W/m.K, and a cohesion of 0.2-0.6 N/25 mm.
