开发多功能离子弹性体,水凝胶和离子凝胶的替代品,将促进高性能离子设备的进步。然而,满足生物衍生的要求,高韧性,高拉伸性,自主自我修复能力,高离子电导率,后处理,和有利的可回收性在单一离子弹性体仍然是一个具有挑战性的努力。在这里,动态共价和超分子设计,硫辛酸(LA)基动态共价离子弹性体(DCIE),提出了通过熔融构建具有分层动态键合的共价自适应网络(CAN-HDB),其中锂键有助于离子的解离和动态二硫化物复分解的整合,锂键,和二元氢键增强机械性能,自我修复能力,后处理,和可回收性。因此,机械多功能性之间的权衡,离子电导率,自我修复能力,后处理,和可回收性成功处理。获得的DCIE显示出显著的拉伸性(1011.7%),高韧性(3877kJm-3),高离子电导率(3.94×10-4Sm-1),自愈能力突出,3D打印的后处理,和理想的可回收性。重要的是,选择性离子传输赋予DCIE多感官特征,能够产生连续的电信号,以获得对温度的高质量感觉,湿度,湿度和应变。再加上简单的方法,充足的LA和HPC可用性,以及多功能,DCIE提出了用于开发软离子电子技术的先进离子导体的新概念。
Developing versatile ionoelastomers, the alternatives to hydrogels and ionogels, will boost the advancement of high-performance ionotronic devices. However, meeting the requirements of bio-derivation, high toughness, high stretchability, autonomous self-healing ability, high ionic conductivity, reprocessing, and favorable recyclability in a single ionoelastomer remains a challenging endeavor. Herein, a dynamic covalent and supramolecular design, lipoic acid (LA)-based dynamic covalent ionoelastomer (DCIE), is proposed via melt building covalent adaptive networks with hierarchically dynamic bonding (CAN-HDB), wherein lithium bonds aid in the dissociation of ions and the integration of dynamic disulfide metathesis, lithium bonds, and binary hydrogen bonds enhances the mechanical performances, self-healing capability, reprocessing, and recyclability. Therefore, the trade-off among mechanical versatility, ionic conductivity, self-healing capability, reprocessing, and recyclability is successfully handled. The obtained DCIE demonstrates remarkable stretchability (1011.7%), high toughness (3877 kJ m-3), high ionic conductivity (3.94 × 10-4 S m-1), outstanding self-healing capability, reprocessing for 3D printing, and desirable recyclability. Significantly, the selective ion transport endows the DCIE with multisensory feature capable of generating continuous electrical signals for high-quality sensations towards temperature, humidity, and strain. Coupled with the straightforward methodology, abundant availability of LA and HPC, as well as multifunction, the DCIEs present new concept of advanced ionic conductors for developing soft ionotronics.
