| titleOfInvention | A kind of preparation method of graphene/copper composite material with high orientation and high thermal conductivity |
| abstract | The invention discloses a preparation method of a graphene/copper composite material with high orientation and high thermal conductivity. The method comprises: 1. preparation of large-diameter graphene oxide dispersion liquid; 2. copper foil surface pretreatment and modification; 3. electrophoresis Depositing and preparing graphene oxide/copper foil with preferred orientation; 4. Folding, stacking and sintering in sequence to prepare highly oriented and high thermal conductivity graphene/copper composite material. The invention adopts electrophoretic deposition on the surface of the modified copper foil to obtain the graphene oxide/copper foil with preferred orientation, which is sequentially folded, stacked and sintered, so that the large-diameter graphene oxide sheets are rotated and arranged in an orderly manner and recombined to form an orderly high orientation Graphene film, taking advantage of the high thermal conductivity of graphene, obtains a highly oriented and high thermal conductivity graphene/copper composite material, which solves the problem of difficult control of dispersion and orientation when graphene is used as a thermal conductivity enhancer, combined with interface modification and copper matrix The three-dimensional network connection improves the overall strength of the graphene/copper composite. |
