▎ 摘　　要

NOVELTY - Preparing biomimetic ceramic-based materials comprises (a) preparing an ordered layered hybrid framework with a biomimetic structure, where the components of the ordered layered hybrid framework include polymers and nano reinforcements; (b) placing the frame of the ordered layered mixture in a mold, injecting the ceramic precursor mother liquor containing polyelectrolyte into mold, and depositing the injected ceramic precursor mother liquor on the frame of the ordered layered mixture to form a ceramic lamellar structure to obtain a ceramic base frame; where the distribution of the nano-reinforcement in the ceramic-based framework in the edge region of the ceramic lamellar structure is greater than that in the central region of the ceramic lamellar structure; and (c) immersing the ceramic-based frame in a polymer solution, and performing hot pressing. USE - The method is useful for preparing bionic ceramic base material based on nano-scale gradient structure optimization. ADVANTAGE - The method controls the ceramic precursor crystal nucleation path, to control the distribution of the nano-reinforced body in the ceramic base material, so as to construct nano-scale fine structure, optimizing each mechanical property of the bionic ceramic material. DESCRIPTION OF DRAWING(S) - The drawing shows an embodiment 1 of the present invention provides a pearl-imitated female structure of nano-graphene-calcium carbonate-calcium carbonate ceramic base material of the Raman surface scanning pattern.
