Abstract

Provided is a nanofiber composite membrane for guided bone regeneration, which includes: spinning a spinning solution by an electrospinning method to produce nanofibers; accumulating the nanofibers, to prepare a certain thickness of a nanofiber web; and drying and thermally calendering the nanofiber web to sterilize the nanofiber web, wherein the spinning solution contains a biocompatible plasticizer to maintain physical properties, flexibility and elasticity of the membrane, by suppressing an increase in brittleness in a sterilization treatment.
