23 Jul Calcium phosphate/zirconium oxide gradient porous scaffold as well as preparation method and application
Abstract
The invention provides a calcium phosphate/zirconium oxide gradient porous scaffold as well as a preparation method and application. The porous scaffold takes calcium phosphate ceramic and zirconium oxide powder as raw materials, is formed through a light curing technology, and is obtained through high temperature degreasing and sintering. The pore size of the porous scaffold forms gradient changebetween 10 to 100 micrometers, the porosity is 30 to 90 percent, and the porous scaffold has relativley high penetration. The method does not need dies, can realize individualized design of scaffoldappearance and porosity and gradient change of the pore size, and can adjust the mechanical property and biological activity of the composite scaffold by controlling the ratio of ceramic powder, thereby obtaining the porous scaffold with excellent biological property and certain strength. The composite porous scaffold prepared with the method has potential application space in the field of bone tissue engineering.
