Abstract Rise and development of flexible electronic devices require stretchable semiconductors, but there remains a striking issue of a destruction in conductive network under large deformation. Herein, inspired by the composition of the deep eutectic solvent (DES), we fabricate an ionic conductive elastomer by doping 1-(2-hydroxyethyl)-3-methylimidazolium chloride ([HOEtMIm]Cl) into acid-hydrolyzed copolymer of n-butyl acrylate (nBA) and tert-butyl acrylate (tBA). As a result, our fabricated acid-hydrolyzed P(nAB-co-tBA)/[HOEtMIm]Cl composites possess superior ductility, high tensile strength (1.86 MPa) and good electrical conductivity (2.03 ×10-6 S·cm-1), meanwhile, there is no sudden drop in resistance during stretching. [HOEtMIm]Cl disperses uniformly in the matrix as it’s associated with the matrix through hydrogen bonding. As an attempt, we demonstrate its application for touch sensor as well as strain sensor.

基于氢键的强且高度可拉伸的离子导电弹性体

摘要 柔性电子器件的兴起和发展需要可拉伸的半导体，但在大变形下导电网络的破坏仍然是一个突出的问题。在此，受深共熔溶剂 (DES) 组成的启发，我们通过将 1-(2-羟乙基)-3-甲基咪唑氯化物 ([HOEtMIm]Cl) 掺杂到酸水解的正丁基共聚物中来制备离子导电弹性体。丙烯酸酯 (nBA) 和丙烯酸叔丁酯 (tBA)。因此，我们制备的酸水解 P(nAB-co-tBA)/[HOEtMIm]Cl 复合材料具有优异的延展性、高拉伸强度 (1.86 MPa) 和良好的导电性 (2.03 ×10-6 S·cm-1)同时，拉伸过程中阻力不会突然下降。[HOEtMIm]Cl 通过氢键与基体结合，因此均匀地分散在基体中。作为尝试，
