结构仿生生物玻璃材料的制备及其性能研究

Bionics is an emerging science following by chemistry, systems biologist, molecular biology and nanotechnology's development. Biomimetic materials science refers to the characteristics of the mechanism research and the structure-activity relationship of biological materials from the molecular level. Biomimetic biomaterials no only need the suitable mechanical and electrical properties, three-dimensional network structure and excellent cell/material interface, but also ask for good biocompatibility. This paper is based on bionic structure principle, Bioglass with bionic structure shows similar structure to natural bone materials and complied with the principle of bionics that was prepared by the secondary hydrothermal method. At the same time, a zeolite molecular sieve was loaded on the silicate nanometers. It can not only increased the surface area and specific surface area of the bioglass to provide larger adhesion space for biological cells, but also increase the biocompatibility and cellular activity of the overall bioglass. Therefore it can promote the adhesion, proliferation and differentiation of the cell on the surface of bioglass. It can be used as a new generation of bone graft or the biological scaffold materials of bone repair.
