近年来,MXene由于其优异的亲水性、导电性、柔韧性而成为制备多重响应执行器的优选材料。然而,现有基于MXene的多重响应执行器普遍存在材料体系与结构复杂的问题,严重制约了其实际应用。因此,开发一种基于简单材料体系的多重响应执行器仍然是一种挑战。通过逐层真空抽滤氧化石墨烯(GO)和MXene形成双层复合膜,开发了一种基于MXene/GO的双层执行器。该执行器能够在湿度、光场、电场的刺激下快速发生形变,有效的将其他形式的能量转化为机械能。响应方式的多样性使该执行器在微机电系统、可穿戴设备、软体机器人等领域展现出广泛的应用前景。该工作为多重响应执行器的开发提供了一种简单的思路。
In recent years,MXene has become the preferred material for preparing multi-responsive actuators due to its excellent hydrophilicity,conductivity,and flexibility.However,existing MXene-based multi-responsive actuators commonly suffer from complex material systems and structures,which severely restrict their practical applications.Therefore,developing a multi-responsive actuator based on a simple material system remains a challenge.A bilayer MXene/GO actuator was fabricated through layer-by-layer vacuum filtration of graphene oxide (GO) and MXene to form a bilayer composite film.This actuator could quickly deform under the stimulation of humidity,light,and electricity,effectively converting other energy into mechanical energy.The diversity of response methods made this actuator widely applicable in fields such as microelectromechanical systems,wearable devices,and soft robots.This work provides a simple approach for the development of multi-responsive actuators.
