In nature, many mysterious creatures capable of
deformation camouflage, color camouflage, and self-healing
have inspired scientists to develop various biomimetic soft
robots. However, the systematic integration of all the above
functionalities into a single soft actuator system still remains a
challenge. Here we chemically introduce a multi-stimuliresponsive
tetraarylsuccinonitrile (TASN) chromophore into
a liquid crystal elastomer (LCE) network through a facile
thiol-ene photoaddition method. The obtained TASN-LCE
soft actuators not only exhibit reversible shape-morphing and
reversible color-changing behavior in response to heat and
mechanical compression, but also show excellent self-healing,
reprogramming and recycling characteristics. We hope that
such a TASN-LCE actuator system endowed with dynamic
distortion, thermo- and mechano-chromic camouflage, and
self-healing functionalities would pave the way for further
development of multifunctional biomimetic soft robotic
devices.
