Summary: A novel approach for 3D-printing BC reinforced UV-curable ion gels using two-component solvents has been demonstrated in this study. The cholinium-based systems showed lower viscosity and improved stability compared to the imidazolium-based ones. The grafting of poly(acrylic acid) onto cellulose nanofibers resulted in higher elongation at break and enhanced mechanical properties for choline chloride-based compositions.

Summary: This study aimed to investigate the influence of water as a co-solvent on the interaction between a polymerizable ionic liquid and bacterial cellulose. It was found that the addition of water reduces the viscosity and yield stress of the solvent, and decreases the stability of dispersion under stress. The optimal composition of ChA/water was determined to ensure printability and stability of the ink.

Summary: This study demonstrates the preparation route of cellulose nanofiber dispersions from bacterial cellulose using ethylene glycol- or glycerol-based deep eutectic solvents (DES). The combined influence of DES treatment and ultrasound on the thermal and mechanical properties of bacterial cellulose nanofibers (BC-NFs) is investigated. The results show that the maximal Young's modulus is achieved with ethylene glycol-based DES and ultrasound treatment, while the maximal strength is achieved with glycerol-based DES and ultrasound treatment. The improved mechanical and thermal characteristics are attributed to the disordering of the BC-NF surface structure and the preservation of high crystallinity bulk.

Summary: Inks for 3D printing were prepared by dispersing methacrylate-functionalized bacterial cellulose nanofibers (CNF) in a polymerizable deep eutectic solvent (DES) with water as a cosolvent. The resulting 3D-printed gels were composed of chemically and physically crosslinked networks formed from modified CNF and polymerized DES, respectively. The addition of water improved the mechanical properties of the composite gel, while an anhydrous system exhibited better shape memory properties.
