Natural sunlight-actuated shape memory materials with reversible shape change and self-healing abilities based on carbon nanotubes filled conductive polymer composites

Light-responsive shape memory materials (SMMs) are a type of smart materials which utilize the convenient light energy to actuate shape changes of the materials. Although natural sunlight is the unlimited and clean energy on the earth, it is still a challenge to use sunlight to trigger shape changes of SMMs because sunlight is a relatively weak energy source. Herein, a type of natural sunlight-actuated SMMs with self-healing ability based on the...
