With the increase of global temperature, ultraviolet radiation intensity and chemical pollutants, the bleaching problem of marine coral reefs is becoming increasingly serious. It is of great significance to develop new coral reef repair materials. The Montipora digitara coral reef (CR) was selected as the research object. On the basis of comprehensive analysis of chemical composition, physical morphology and mechanical properties on CR, white cement was used as the matrix to simulate the chemical composition and physical structure of the coral reef, by adding foaming agent (LG-2258), calcium carbonate, calcium bicarbonate and chitosan (CS) to prepare Coral reef biomimetic materials. The structure and properties of natural coral reefs and bioinspired materials were measured by SEM, FTIR, EDS, ICP-OES and universal testing machine. The results showed that the biomimetic materials had similar pore structure, mechanical properties and chemical composition with the natural coral reefs. After six months of cultivation on the surface of biomimetic materials, coral plants got 10.36 mm increase on height, and the polyps could attach to the surface of the biomimetic material and form new coral tissue.
