  该研究为设计和制备强收缩、高能量密度、多形变模式的水凝胶材料提供了新策略。相关研究成果以Bioinspired high-power-density strong contractile hydrogel by programmable elastic recoilBG视讯网为题,发表在上。兰州化物所为论文的第一单位,博士马延飞、华牧天为论文的共同第一作者,贺曦敏、周峰为论文的共同通讯作者。此前,周峰团队发明了利用铁离子-羧酸根的强配位作用构筑超高机械强度和韧性的水凝胶体系();通过拉伸状态下固定分子构象制备出各向异性结构的水凝胶,将水凝胶的拉伸强度提升到40MPa(),为该课题奠定了基础。研究工作得到国家自然科学基金、中科院国际合作项目、国家重点研发计划,美国国家科学基金会等的支持。
