HydrogeleSol-Gel-ProzesseInspired by the anti‐freezing mechanisms found in nature, ionic compounds (ZnCl2/CaCl2) are integrated into cellulose hydrogel networks to enhance the freezing resistance. In this work, cotton cellulose is dissolved by a specially designed ZnCl2/CaCl2 system, which endows ...
In addition, the hydrogel solution has good injectability, gelling rate controllability, and biocompatibility, which makes it a good candidate in 3D printing. In summary, the hydrogel developed in this study has good application scenarios for applications such as electronic skin, flexible wearable ...
If conductive hydrogels can be made into one-dimensional fibers with ordered alignment of polymer chains, some properties of conductive hydrogel fibers (e.g., mechanical properties and conductivity) would be greatly enhanced over conventional conductive hydrogel films and monoliths17. However, the ...
Ideal hydrogel fibers with high toughness and environmental tolerance are indispensable for their long-term application in flexible electronics as actuating and sensing elements. However, current hydrogel fibers exhibit poor mechanical properties and environmental instability due to their intrinsically weak mole...
