导电水凝胶由于具有优异的柔韧性、拉伸性及导电性等可用作柔性传感器,但是由于其本身的亲水性,传统水凝胶的抗溶胀性能较差,在水环境中会导致水凝胶的力学性能大幅下降,限制了导电水凝胶在水下环境中的应用。为了提高水凝胶的抗溶胀性能,可以通过亲水-疏水协同作用或交联改性来提高水凝胶的抗溶胀性能。综述了抗溶胀水凝胶的制备方法,重点阐述了交联成型制备抗溶胀水凝胶的方法,并对抗溶胀导电水凝胶在柔性传感器方面的应用研究进行了介绍。
Conductive hydrogels can be used as flexible sensors due to their excellent flexibility,stretchability,and conductivity.However,owing to its inherent hydrophilicity,traditional hydrogels exhibit poor anti-swelling properties,leading to a significant decline in mechanical performance in aquatic environment and limiting the application of conductive hydrogels in underwater environments.To enhance the anti-swelling capability of hydrogels,hydrophilic-hydrophobic synergistic effect or crosslinking modification can be employed to improve their anti-swelling properties.This article reviewed the preparation methods of anti-swelling hydrogels,with a focus on elucidating the methods of preparing anti-swelling hydrogels through crosslinking molding,and introduced the application research of anti-swelling conductive hydrogels in flexible sensors.
