摘　　要：介电弹性体是一类响应于外加电场而产生形变的智能高分子材料.因为其柔顺性、快速响应性和可寻址性,介电弹性体及其驱动器被视为一种具有广阔应用前景的人工肌肉技术.分子设计在各个尺度影响介电弹性体的性能:分子结构改变材料在电场下的极化能力,聚合物网络结构设计影响材料在力电耦合过程中的变形能力,影响器件制造的加工方式.本文结合本课题组在该领域的研究,从分子、材料和器件三个层次综述介电弹性体的设计原则.Dielectric elastomers are a class of smart polymer materials that deform in response to an electric field.Due to their flexibility,rapid responsive,and addressability,dielectric elastomers are considered as an artificial muscle technology with broad applications.Molecular design affects the performance of dielectric elastomers at all scales:the molecular structure changes the polarization ability of the material under an electric field,and the design of polymer network structure affects the deformation ability of the material during electromechanical coupling and the processing method of device manufacturing.Based on the research experience of our research group in this field,this paper reviews the design principles of dielectric elastomers from three levels:molecules,materials,and devices.
