23 Jul Mesoporous calcium magnesium silicate/wheat protein composite material as well as preparation method and application of composite material
Abstract
The invention discloses a mesoporous calcium magnesium silicate/wheat protein composite material as well as a preparation method and an application of the composite material. The method comprises the following steps: (1) mixing a mixture of mesoporous calcium magnesium silicate, wheat protein and a pore-foaming agent with a solvent A evenly to obtain slurry; (2) extruding and molding the slurry obtained from the step (2) to obtain a precursor; and (3) soaking the precursor obtained from the step (2) into a solvent B, removing the pore-foaming agent, and carrying out freeze drying. The preparation method disclosed by the invention is relatively simple and relatively high in repeatability and stability; the prepared composite material has a multi-stage aperture structure, has large specific surface area and good mechanical property, can form an active interface together with tone tissues when being implanted into a body, and has good biological activity; a good growth environment is provided for cells; the composite material can be continuously degraded in Tris-HCl and PBS buffer solutions; regeneration of tissue cells is regulated and controlled, so that the bone tissue is successfully repaired; and the composite material has potential application prospect in the field of bone tissue engineering.
