Shape-Memory Hydrogels: Evolution of Structural Principles To …
Webb22 mars 2024 · These hydrogel muscles exhibited a high actuation rate, large actuation strain, and shape memory property in response to solvents. It has been found that during these external stimulus processes, the shrinkage and crispation of the helixes will usually be guided by the microstructure change of materials. 8 WebbThis is manifested in highly stretched, twisted, and knotted hydrogel strips that can rapidly recover their original shape in a dilute salt solution. The high strength and modulus, ionic stimuli response, and shape memory property make the hybrid hydrogel a promising material for bioactuators in various biomedical applications.
