加州大学河滨分校、科罗拉多大学博尔德分校的研究人员联合开发出一种拥有自愈能力的透明、高延展性导离子材料。这种材料可赋予机器人发生机械故障后的自愈能力延长锂离子电池的使用寿命,改善医学和环境监控领域生物传感器的性能等,应用前景广阔。离子导体内允许离子在其中流动,在能源储存、太阳能转换、传感器和电子设备中扮演着重要的角色。此前,研究人员研制的离子导体能够为人造肌肉供能并用其制成透明扬声器,但出现机械故障后不能自愈。在新的研究中,研究人员利用离子偶极作用,使带电离子与极性分子之间耦合,从而大幅提高了离子导体的稳定性,最终研制出了 Researchers at the University of California, Riverside and the University of Colorado Boulder have jointly developed a self-healing, transparent, highly ductile, ion-conducting material. This material can give the robot a self-healing ability after a mechanical failure to extend the service life of lithium-ion batteries and improve the performance of biosensors in the field of medical and environmental monitoring. The application prospect is promising. Ionized ions allow ions to flow in and play an important role in energy storage, solar energy conversion, sensors and electronics. Previously, researchers developed ion conductors that could power artificial muscles and use them to make transparent loudspeakers, but failed to heal themselves after a mechanical failure. In a new study, researchers used ionic dipoles to couple electrically charged ions to polar molecules, dramatically increasing the stability of ion conductors and eventually developing
