Self-repairing degradable porous conductive gel material as well as preparation method and application thereof

The invention provides a self-repairing degradable porous conductive gel material as well as a preparation method and application thereof. The self-repairing degradable porous conductive gel materialis obtained by compounding a natural polymer material-sodium aginate with a non-toxic material-polyvinyl alcohol to form a gel network skeleton, carrying out cross-linking through an anionic surfactant and carrying out cyclic freezing-unfreezing treatment. According to the self-repairing degradable porous conductive gel material provided by the invention, the size of an inner porous channel is uniform and controllable, and the self-repairing degradable porous conductive gel material has good conductivity, stronger mechanical performance and stronger self-repairing performance, is degradable and has good biocompatibility. 本发明提供了种自修复可降解多孔导电凝胶材料及其制备方法和应用。本发明以天然高分子材料海藻酸钠复合无毒材料聚乙烯醇为凝胶网络骨架，由阴离子表面活性剂交联，通过循环冷冻-解冻处理得到自修复可降解多孔导电凝胶材料。本发明提供的多孔导电凝胶材料内部孔道大小均可控，具有优良的导电性能，具有较强的机械性能及自修复性能，且可降解，具有良好的生物相容性。
