▎ 摘　　要

NOVELTY - Preparing vertical graphene-based thermal interface material comprises preparing vertical graphene through plasma-enhanced chemical vapor deposition process under the action of an electric field, where the direction of the electric field is the same as the growth direction of the vertical graphene. USE - The method is useful for preparing vertical graphene-based thermal interface material. ADVANTAGE - The method: adopts simple device; and has simple process flow and strong repeatability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) vertical graphene-based thermal interface material prepared by the above method; and (2) device for preparing vertical graphene-based thermal interface material, including chemical vapor deposition furnace, plasma source and electric field generating component. The electric field generating component includes a first electrode plate, a second electrode plate and a direct current power supply. The first electrode plate and the second electrode plate are both arranged in the reaction chamber of the chemical vapor deposition furnace. The first electrode plate is connected to the cathode of the DC power supply. The second electrode plate is connected to the anode of the DC power supply. The first electrode plate is located above the second electrode plate.
