▎ 摘 要
NOVELTY - The method involves (i) taking the carbon fiber bundle, wrapping a layer of aluminum foil on the carbon fiber bundle, exposing a bare end and using pulse laser vapor deposition device to deposit cobalt film on the exposed end; (ii) detecting the magnetism of the cobalt film deposition end on the carbon fiber bundle, if the magnetic is not enough, re-depositing the cobalt film and if the magnetism meets the requirement, entering step (iii); (iii) placing the carbon fiber beam in the copper hydroxide/graphene oxide suspension and ultrasonic dispersion to obtain the mixed solution; (iv) arranging the carbon fiber bundle in the mixed liquid in multi-stage orientation and passing the top end of the carbon fiber bundle through the top surface of the mixed liquid; (v) subjecting the mixed solution through bidirectional freezing gradient and freeze-drying to form carbon fiber bundle-copper hydroxide/graphene oxide heat conducting material; and (vi) reducing the material to form material. USE - The method for preparing graphene adding/radiating composite material is useful for energy automobile lithium battery. ADVANTAGE - The carbon fiber bundle in the mixed liquid is highly oriented by multi-level magnetic arrangement, and improves the product heat conducting coefficient by more than 30%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene adding/radiating composite material, is prepared as mentioned above. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of a multi-level magnetic arrangement region of a of graphene adding/radiating composite material for new energy automobile lithium battery. 100Outer ring iron core
