Summary: In this study, a bacterial cellulose (BC) derived hydrogel membrane with a double-network (DN) structure and tailored ion transport channels was reported. The fabricated AAM/BC DN hydrogel membrane displayed a unique hierarchical interconnected porous structure and 3D cation transport channels. The results showed that it achieved a maximum power density of 7.63 Wv at a 50-fold salinity gradient under alkaline conditions (pH 11). Additionally, it obtained a power density of 45.5 W·m(-2) through acid-base neutralization reaction, and 28.4 W·m(-2) from a mixed system of paper black liquor wastewater/seawater. The investigation suggested the enormous potential of BC-based nanofluidic membrane in sustainable osmotic energy conversion.

Summary: Inspired by muscle architecture, an anisotropic cellulose nanofiber (CNF) based double-network conductive hydrogel containing oriented MXenes was fabricated. The resulting hydrogel exhibited superior performance in terms of strength, toughness, and conductivity, with values of 3.33 MPa, 1106%, and 13.08 S/m, respectively, surpassing most reported hydrogels. Due to its excellent conductivity and mechanical properties, the anisotropic hydrogel could be used in the development of multi-functional flexible electronics, such as flexible touch panels and highly sensitive and stable strain/pressure sensors. With its superior compatibility for human-computer interaction, the hydrogel wearable sensor holds promising potential for real-time wireless monitoring of human motion and real-time control of robots.

Summary: The study aims to understand the relationship between the network structure and properties of bacterial cellulose (BC) hydrogels, and proposes a method for quantitative evaluation of nanofibril network structure. Various BC hydrogels with different network structures were prepared from seven bacterial strains, and the crosslink densities of the gels were determined quantitatively. Tensile tests showed that the stress-strain curves of BC hydrogels exhibited strain hardening, and the power exponent had a linear relationship with the crosslink density. This provides insights into the structure-property relationships of BC hydrogels for quality control, process optimization, and property prediction.
