23 Jul Preparation method of biomimetic gradient porous ceramic material
Abstract
The invention discloses a preparation method of a biomimetic gradient porous ceramic material. The method includes: subjecting a ceramic slurry to freezing, then conducting vacuum freeze drying, and finally performing sintering, thus obtaining the biomimetic gradient porous ceramic material. The preparation method of the biomimetic gradient porous ceramic material provided in the invention combines slip casting and repeated freeze drying technologies, and the obtained gradient porous ceramic material has porosity decreasing from inside to outside and a biomimetic structure with a sparse inside and a dense outside. While functions of the pores are ensured, the biomimetic gradient porous ceramic material has good mechanical properties, its gradient interface changes continuously, and at the same time, the gradient change range is controllable, so that the biomimetic gradient porous ceramic material has wide application prospects in the fields of biological tissue engineering, filter materials, catalyst carriers, and fuel cells, etc.
