摘要：Hydroplastic polymers have attracted much attention due to their good combination of hydroformability and environmental sustainability. However, the instability of the network structure of hydroplastic polymers constructed from a single non-covalent physical interaction makes it challenging to achieve satisfactory mechanical properties and hydroforming simultaneously. Herein, a cellulose hydroplastic polymer (Cel-hydroplastic) was proposed that is fabricated by constructing a dynamic dual cross-linking network (boronic ester and hydrogen bonds) between cellulose nanofibers (CNF) and synthetic copolymer containing a catechol structure (PHD). Notably, CNF promotes water-driven reorganization of the dynamic dual network, which allows Cel-hydroplastic to switch arbitrarily between 2D and 3D shapes. Meanwhile, introducing CNF enables Cel-hydroplastic with high mechanical strength (tensile strength: 128.30 MPa dry; 44.50 MPa at relative humidity 90 %). Furthermore, Celhydroplastic can be easily recycled and efficiently biodegraded in natural environments. Overall, these outstanding properties position Cel-hydroplastic as a promising candidate for the next generation of environmentally friendly materials.
