BIODEGRADABLE POROUS POLYMER SCAFFOLDS BY USING EFFERVESCENT MIXTURE FOR TISSUE ENGINEERING AND THEIR PREPARATION METHODS

摘要

The present invention relates to a method for preparing a biodegradable porous polymer support for tissue engineering, wherein the method is used to prepare a polymer specimen using a polymer solution containing a biodegradable polymer and an effervescent mixture, followed by boiling under a boiling medium such as an alcohol mixed solution. (Foaming) and drying.;The present invention also relates to a biodegradable porous polymer support for tissue engineering prepared by the above method, wherein the biodegradable porous polymer support is easy to control pore size, has high porosity, and is continuously connected to a bubble structure (open space). cell structure).;The biodegradable porous polymer support according to the present invention and a method for producing the support are generated by a salt leaching technique and a gas foaming technique which have been generally applied in the manufacture of a conventional polymer scaffold. It is an alternative to solve the porous clogging of the surface, the complex manufacturing process and the secretion and remaining of harmful substances, and has the advantage of being able to regenerate almost all tissues and organs by tissue engineering.
