The embodiment of the invention provides an adhesion thermo-sensitive hydrogel of composite bioglass. The adhesion thermo-sensitive hydrogel is prepared from the following components in percentage byweight: 25-40% of PDLLA-PEG-PDLLA triblock polymer, 1-1.25% of dopamine modified quaternized chitosan, 1-5% of bio-glass and the balance of deionized water. The adhesion thermo-sensitive hydrogel of the composite bioglass has good adhesion, antibacterial property and biocompatibility. The adhesion thermo-sensitive hydrogel of the composite bioglass can self-adhere to the surface of the skin wound,and is beneficial for promoting skin regeneration and wound repair. The invention further provides a preparation method and application of the adhesion thermo-sensitive hydrogel of the composite bioglass. The preparation method is simple in process and high in yield, and is suitable for large-scale industrial production. The adhesion thermo-sensitive hydrogel of the composite bioglass prepared bythe preparation method has good adhesion, antibacterial property and biocompatibility, and has broad application prospects in the preparation of drugs for skin wound healing.
