A method for fabricating three-layer porous bioactive membranes using spin coating technology and freeze-drying technology and three-layer porous bioactive membranes fabricated by the method

摘要

A biologically active membrane production method by fusion of a spin coating technique and a freeze-drying technique and a bioactive membrane produced thereby are disclosed. According to an embodiment of the present invention, there is provided a method of manufacturing a bioactive film, comprising: (a1) preparing a polymer solution including a biodegradable polymer and a solvent; (a2) forming a thin film of the polymer solution by spin coating; (a3) freezing the thin film; And (a4) drying the thin film by sublimating the solvent in the frozen thin film.
