The invention discloses a method for preparing 3D interlocked graphene interface tough ceramic, which comprises the following steps: by taking methanol as a precursor, growing vertical graphene on the surface of ceramic powder in situ through a low-pressure chemical vapor deposition method to realize uniform and large-area coverage of the graphene on the surface of the ceramic powder to obtain composite ceramic powder deposited with the vertical graphene, and drying the composite ceramic powder to obtain the 3D interlocked graphene interface tough ceramic. The composite ceramic powder deposited with the vertical graphene is subjected to hot pressed sintering, the composite ceramic with the tough 3D interlocking graphene interface is obtained, and by means of the method, the weak anti-shearing capacity between graphene layers can be enhanced.

本发明公开了一种3D互锁石墨烯界面强韧陶瓷的方法，包括：以甲醇为前驱体，通过低压化学气相沉积法，在陶瓷粉末表面原位生长垂直石墨烯，实现石墨烯在陶瓷粉末表面的均匀以及大面积覆盖，得沉积有垂直石墨烯的复合陶瓷粉末，将所述沉积有垂直石墨烯的复合陶瓷粉末进行热压烧结，得3D互锁石墨烯界面强韧的复合陶瓷，该方法能够实现石墨烯层间弱抗剪切能力的增强。
