Graphene/ceramic layered material preparing method
The invention belongs to the technical field of ceramic materials, and particularly relates to a graphene/ceramic layered material preparing method. The purpose is to solve the problems that a traditional method for preparing a layered ceramic material through tape casting or film rolling forming is tedious in process and high in cost. The preparing method includes the steps that layered ceramic blanks containing oxidized graphene are prepared to obtain a layered ceramic blank A containing oxidized graphene, a layered ceramic blank B containing oxidized graphene, a layered ceramic blank C containing oxidized graphene and a layered ceramic blank D containing oxidized graphene; hot pressed sintering is carried out, wherein the layered ceramic blanks are loaded into a mold in an alternately stacked mode, and hot pressed sintering is carried out under the vacuum or argon inert atmosphere protection condition to obtain a graphene/ceramic layered material. The graphene/ceramic layered material has the advantages that the room temperature fracture toughness is 8-10 MPa.m0.5, and the three-point bending strength is 400-600 MPa. The invention is mainly used for preparing the graphene/ceramic layered material.
