摘要
水凝胶基柔性聚合物材料,因其优异的传感性能、良好的延展性,广泛应用于智能可穿戴应变传感器领域。然而,传感器件在使用过程中,会发生信号干扰,影响设备的正常运转。因此,开发兼具有应变传感和电磁屏蔽双功能的水凝胶材料具有重要意义。本文介绍了水凝胶材料的应变传感及电磁屏蔽机制,分析了微观结构、溶剂种类、导电填料种类和导电网络结构对双功能水凝胶材料性能的影响,并根据目前双功能水凝胶的研究现状,提出了该领域的发展方向和应用前景。
Hydrogel-based flexible polymer materials have received increasing attention due to their excellent sensing performance and superior ductility with application in smart wearable devices.However,the widespread use of intelligent wireless electronic wearables equipment has also produced severe electrical signals interference and radiation.The electrical signals interference generated by wearable devices significantly affects the performance of apparatuses.Therefore,it is important to develop hydrogel materials with dual functions of strain sensing and electromagnetic shielding.This review begins with presenting on strain sensing and electromagnetic shielding mechanism of hydrogel materials.At the same time,the effects of microstructure,solvent type,conductive filler type and conductive network structure on the properties of bifunctional hydrogel materials are analyzed.Finally,according to the current research status of bifunctional hydrogels,the development direction and application prospect of bifunctional hydrogels are proposed.
