| The preparation process is the key to adjust the structure of graphene/ceramic composites and optimizing their mechanical and thermoelectric properties. The work reviewed the powder compact sintering process and 3D printing technology of graphene/ceramic composites and their research progress. The powder compact sintering process included pressureless sintering, hot pressing sintering, spark plasma sintering, microwave sintering and high-frequency induction heating sintering, etc. It had the advantages of simple process, good material properties, and easy control of preparation parameters. This was the main preparation process of graphene/ceramic composites, which was used to prepare dense bulk composites. The main 3D printing processes included direct writing molding, laser selective sintering, inkjet printing and stereo light curing, etc., which had the characteristics of controllable structure and shape. It was the current research hotspot of graphene/ceramic composite materials, which was used to form composite devices with complex shapes and specific properties. In addition, the preparation process of graphene/ceramic composites using specific physical and chemical reactions such as in-situ generation method and carbothermic reduction method were briefly introduced, and the dispersion process of graphene in composite materials was reviewed. |
