Cleavable material precursor polymer, cleavable material and preparation method of precursor polymer

The invention discloses a cleavable material precursor polymer, a cleavable material and a preparation method of the precursor polymer. The prepared precursor polymer of the cleavable material is endowed with photocuring performance and controllable cracking performance by introducing olefin functional groups coupled by cleavable chemical bonds to precursor macromolecules. The prepared cleavable material comprises hydrogel and a freeze-dried porous scaffold of the hydrogel, and the cleavable material is rapidly cleaved into a solution under the action of a cleavable reagent. The cleavable material prepared by the invention has a wide application prospect in the fields of cell culture and tissue engineering. 本发明公开了一种可裂解材料前驱体聚合物、可裂解材料及其制备方法。本发明所制备的可裂解材料前驱体聚合物是通过在前驱体高分子上引入可裂解化学键偶联的烯烃官能团，赋予前驱体材料光固化性能和可控裂解性能。本发明所制备可裂解材料包括水凝胶及其冻干多孔支架，该可裂解材料在裂解试剂作用下快速裂解为溶液。本发明所制备可裂解材料在细胞培养及组织工程领域有广阔应用前景。
