A preparation method of calcium peroxide-mediated in situ crosslinkable hydrogel as a sustained oxygen-generating matrix, includes: a) reacting a natural or a synthetic polymer with Traut's reagent (TR) in a solvent, and synthesizing a polymer derivative having thiol group in backbone of the polymer derivative; and b) mixing and reacting a solution of the polymer derivative having thiol group with calcium peroxide (CaO2), and thereby forming a hydrogel, wherein in the step b), disulfide bonds (—S—S) are induced between backbones of the polymer derivative having thiol group attached by decomposition of calcium peroxide (CaO2), and thereby in situ crosslinking is formed. |
