摘要

This study reports a novel amphiphilic polymer liquid crystal composite films with good programmed shape deformation behavior and humidity-responsive self-healing properties by simple mixing amphiphilic polymers and liquid crystal azobenzene compounds in solution.

Abstract

In this study

a zwitterionic polymer/liquid crystals composite film with programming shape-morphing behavior and humidity-responsive self-healing performance was prepared by blending a zwitterionic polymer and liquid crystalline azobenzene compound in solution

followed by film-forming in a mold without tedious or multistep synthetic route. The as-obtained zwitterionic polymer/liquid crystal composite film exhibited programming shape-morphing behavior under different stimuli. In this process

the temporary shape of the composite film was memorized after the removal of the stimuli. Such characteristics would fit the requirements of intelligence and energy-saving for stimuli-responsive shape-changing materials. Moreover

the composite film showed humidity-responsive self-healing performances under wet conditions at room temperature. In summary

the simple design and preparation route of the zwitterionic polymer/liquid crystal composite film with programming shape-morphing behavior and mild condition-responsive self-healing performance look promising for the fabrication and practical application of novel photo-driven devices and soft robotics.
