Abstract

Nanocellulose has aroused extensive interests in materials engineering and design owing to its great potential in fabricating robust architectures for diverse applications and functionalities. On the other hand, the sensitivity of cellulose to water results in the deterioration of strength, durability, and functionality thus unsuitable for advanced applications. To address this challenge, we present an efficient, sustainable and scalable strategy to convert cellulose into an advanced biomaterial by integration with a green hydrogen bonded slurry. The resultant cellulose hybrid slurry was cast and cured to fabricate strong and tough biofilms. The hydrogen bonded slurry was revealed to promote tight rapping of the nanofibers resulting to a compact structure with an enhanced performance. The dry and wet tensile characteristics of the cellulose hybrid biofilms (375.1 MPa and 160.0 MPa) were much improved compared to the neat cellulose film. The hybrid biofilms also possess excellent UV shielding characteristics, hydrophobicity and a unique antioxidant activity. Of particular interest, the hybrid biofilms can be readily recycled or biodegraded at end of life, hence promoting a circular
