▎ 摘　　要

NOVELTY - Preparation of anti-fatigue hydrogel involves (1) directionally freezing and drying a precursor solution to obtain a hydrogel precursor, (2) immersing the hydrogel precursor obtained in the step (1) in water, and (3) adjusting crystal domains by adding crystal nucleus in the precursor solution, applying external field force during the directional freezing process, or applying an external field force to the hydrogel precursor, and subjecting a component to any one or two of the temperature-controlled quenching treatments. USE - Preparation of anti-fatigue hydrogel used for bioelectronic equipment and personalized medical equipment (all claimed). ADVANTAGE - The method enables simple preparation of anti-fatigue hydrogel having excellent toughness and fatigue resistance, and high productivity.
