Preparation method of high-strength and high-toughness shell-imitated transparent composite material
The invention belongs to the field of materials, and relates to the technical fields of nanomaterial science, bionics, optics and the like, in particular to a preparation method of a high-strength and high-toughness shell-imitated transparent composite material. Graphene oxide-silicon dioxide nanosheets are obtained through a liquid phase synthesis method, then the shell-imitating composite material is prepared by means of vacuum-assisted suction filtration, and finally the high-strength and high-toughness shell-imitating transparent composite material is prepared through sintering. The specific method comprises the following steps: (1) mixing graphene oxide with a silicon source to prepare a graphene oxide-silicon dioxide nanosheet dispersion liquid; (2) preparing a sintering aid solution, and dissolving an organic matter adhesive at the same time; (3) mixing the dispersion liquid in the step (1) and the solution in the step (2) to form slurry, and performing vacuum-assisted suction filtration to obtain a composite film; and (4) carrying out high-temperature sintering on the film obtained in the step (3) to finally realize the preparation of the high-strength and high-toughness shell-imitating transparent composite material.
