Rapid photo-thermal response shape memory driver as well as preparation method and application thereof

The invention discloses a rapid photo-thermal response shape memory driver as well as a preparation method and application thereof. A substrate of the driver is a flexible substrate fiber membrane with a micro-nano fiber structure and a shape memory function, and cellulose nanocrystalline and a conductive two-dimensional MXene material are deposited on the flexible substrate fiber membrane. The photo-thermal response speed of the shape memory driver is high, and the temperature of the surface of the shape memory driver can rapidly reach 80 DEG C or above within 20 s under the stimulation of near-infrared rays of 80-140 mW/cm . 本发明公开了一种快速光热响应的形状记忆驱动器及其制备方法和用途，其基底为具有微纳米纤维结构和形状记忆功能的柔性基底纤维膜，所述柔性基底纤维膜上沉积有纤维素纳米微晶与导电二维MXene材料。本发明的形状记忆驱动器的光热响应速度快，在80～140mW/cm2的近红外刺激下，形状记忆驱动器表面的温度在20s内可以快速达到80℃以上。
