Beschreibung
Zusammenfassung:	PURPOSE: A biodegradable flexible material based on ultraviolet ray and a method for preparing the same are provided to improve the mechanical characteristic of the material based on the cross-linked structure of the material. CONSTITUTION: A biodegradable flexible material is a mixture containing polyethylene oxide, polyurethane, and a photo-initiator. The polyethylene oxide is cross-linked to form the biodegradable flexible material based on a radical bond. The molecular weight of the polyethylene oxide is between 100,000 and 300,000 g/mol. The polyurethane is water-soluble or waterborne polyurethane. The content ratio of the polyethylene oxide and the polyurethane is between 10:90 and 50:50 weight%. The photo-initiator is selected from a group including carbonate, benzotriazole-based elements, benzophenone-based elements, substituted or non-substituted benzoic ester, acrylate, and sterically hindered amine-based elements.
