基于低共熔体系的纳米复合凝胶的制备及其在柔性传感中的应用
Preparation of nanocomposite gel based on deep eutectic system and its application in flexible sensors
摘要
Abstract
In order to solve the problem of poor freezing resistance and weak adhesiveness of current gel-based flexible sensors,highly stretchable(>800%),transparent(>80%)and conductive(>0.19S/m)nanocomposite gel(NC-DES gel)with self-adhesiveness and anti-freezing capacity were prepared in the mixture of water and low eutectic solvent(DES)consisting of choline chloride and urea,using alumina nanoparticles(Al2O3 NPs)as inor-ganic crosslinking agent and acrylic acid(AA),hydroxyethyl methacrylate(HEMA),methacryloxyethyl sulfobe-taine(SBMA)as monomers,respectively.It was found that the prepared NC-DES gel can not only firmly ad-here to the surface of various substances such as skin,glass and plastic,but it also can deform along with the skin without interface separation.At the same time,different behaviors of human body can be rapidly,repeated-ly and stably monitored through the change of electrical resistance.The flexible sensors based on NC-DES gel show high strain sensitivity,wide strain detection range and good stability,which holds broad application pros-pects in the fields of human-computer interaction,health monitoring and motion.monitoring.关键词
