Construction of Near-Infrared Light Controlled Reciprocating Piston “Pump” Based on Soft Actuators with Fluorine-Containing Alternating Polymer

Abstract

Stimuli-responsive liquid crystal polymer networks (LCNs) carve 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, a prototype of photocontrolled reciprocating piston “pump” is designed based on near-infrared (NIR) responsive LCNs with alternating fluorine-containing polymer chains for the first time. The introduction of fluorinated polymer chains greatly enhances mechanical strength, extends durability of the LCNs, and correspondingly results in a 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 NIR-controlled pump as prepared can transport 0.5 mL liquid each cycle (35 s) and work more than 1.0 h uninterruptedly without any manually assisted operation.
