摘要：

High stiffness of hydrogen-bond network generally endows cellulose hydrogels with weak mechanical flexibility and shape uncontrollability, imposing restrictions on their application scopes. Herein, a flexible polyvinyl alcohol (PVA) network is penetrated through the rigid network of bamboo cellulose, inducing the formation of a dual-crosslinked hydrogel with superior flexibility and shape controllability. Besides, the borax crosslinker offers the bamboo nanocellulose-borax-PVA hydrogel with remarkable self-healing ability and high ionic conductivity. The hydrogel achieves a minimum sensing wei...
