Abstract
The present disclosure relates to a biodegradable polymer-gelatin hydrogel composite, a method for preparing the same and a medical implant including the biodegradable polymer-gelatin hydrogel composite. The multi-layered biodegradable polymer-gelatin hydrogel composite of the present disclosure, wherein the biodegradable polymer membrane of a 3D reticular structure and the gelatin hydrogel are stacked, has superior durability and resilience and may exhibit improved elasticity and swellability upon wetting under hydration environment. In addition, it can be shrunk down to 50% of its initial volume upon drying and can maintain elasticity even after the shrinkage. Furthermore, when used in a medical implant, it can protect the joint from the frictional environment in the body, reinforce the muscle torn or ruptured by trauma, relive pain by maintaining space, and induce the improvement of symptoms.
