On the basis of the thermoreversible sol–gel transition behavior of κ-carrageenan in water, a double-network (DN) hydrogel has been fabricated by combining an ionically cross-linked κ-carrageenan network with a covalently cross-linked polyacrylamide (PAAm) network. The κ-carrageenan/PAAm DN hydrogel demonstrated an excellent recoverability and significant self-healing capability (even when notched). More importantly, the warm pregel solution of κ-carrageenan/AAm can be used as an ink of a three-dimensional (3D) printer to print complex 3D structures with remarkable mechanical strength after UV exposure. Furthermore, the κ-carrageenan/PAAm DN hydrogel exhibited a great strain sensitivity with a gauge factor of 0.63 at the strain of 1000%, and thus, the hydrogel can be used as sensitive strain sensors for applications in robotics and human motion detection.

用于3D打印和应变传感器的超拉伸和自修复双网络水凝胶
基于κ-角叉菜胶在水中的热可逆溶胶-凝胶转变行为,通过将离子交联的κ-角叉菜胶网络与共价交联的聚丙烯酰胺(PAAm)结合,制备了双网络(DN)水凝胶。网络。κ-角叉菜胶/ PAAm DN水凝胶具有出色的可回收性和显着的自我修复能力(即使有缺口)。更重要的是,κ-角叉菜胶/ AAm的温暖的预凝胶溶液可以用作三维(3D)打印机的墨水,以在紫外线照射后打印出具有显着机械强度的复杂3D结构。此外,κ-角叉菜胶/ PAAm DN水凝胶在1000%应变下表现出很大的应变敏感性,应变系数为0.63,因此,
