Abstract
A novel electrospun shape memory actuator featuring rapid near-infrared (NIR) responsiveness was fabricated by depositing Ti3C2Tx (MXene)/cellulose nanocrystals (CNCs) hybrids onto fibril mats. The CNCs significantly enhanced the mechanics and photothermal effect of the composite mats. The plateau temperature under the NIR exposure was up to 117 °C within 25 s. By optimizing hybrid compositions, the actuator was capable of lifting an object with the weight of 265 times by height of 80% extension within 10 s. The findings may greatly benefit exploration of electrospun intelligent polymers to actuate in remote manner.
