Abstract:
A phosphazene-based polymer hydrogel with a chemical cross-linkings formed by radiating ultraviolet (UV) and/or mixing with cross-linking agent and/or enzyme, and a method of preparing the same are provided. The hydrogel shows a sol-gel behavior and has an excellent solidity by containing the phosphazene-based polymer that is capable of cross-linking at a certain concentration.
