Stimuli-responsive liquid crystal polymer networks (LCNs) have carved a new path for remote actuation and soft actuators. However, it is still a great challenging work to prepare LCNs with excellent high strength and anti-fatigue properties fitting the transmission model. Herein, for the first time, a prototype of a photocontrolled reciprocating piston “pump” is designed based on near-infrared (NIR) responsive LCNs with alternating fluorine-containing polymer chains. The introduction of fluorinated polymer chains greatly enhances the mechanical strength, extends the durability of the LCNs, and results in the rapid, accurate and lasting NIR-controlled transportation of liquid via the model pump. Amazingly, if the NIR light source is fixed to cycle on for 15 s and off for 20 s automatically, the as-prepared NIR-controlled pump can transport 0.5 mL of liquid each cycle (35 s) and work uninterruptedly for more than 1.0 h without any manually assisted operation.

基于含氟交替聚合物的软执行器构造近红外光控往复活塞“泵”

刺激响应的液晶聚合物网络（LCN）为远程驱动和软驱动器开辟了一条新途径。然而，制备具有优异的高强度和抗疲劳性能的LCN符合传输模型仍然是一项艰巨的工作。在此，首次基于具有交替的含氟聚合物链的近红外（NIR）响应LCN设计光控往复活塞“泵”的原型。氟化聚合物链的引入极大地提高了机械强度，延长了LCN的耐用性，并通过NIR控制了液体的快速，准确和持久传输，模型泵。令人惊讶的是，如果将NIR光源固定为自动开启15 s，关闭自动20 s，则准备好的NIR控制泵可以在每个循环（35 s）中输送0.5 mL液体，并且连续工作超过1.0 h无需任何人工协助的操作。
