Dynamic 3D structures are capable of reversible shape morphing upon the application of external stimuli.Once formed

those structures are hard to be reconfigured.Moreover

their maintenance and low temperature resistance act as another two unaddressed but practical issues.Recently

those challenges are tackled by dispersing carbon nanotubes into liquid crystalline vitrimers.Various dynamic 3D structures can be made by just shining light on the polymer films of nanocomposites in minutes.Those structures can be easily reconfigured

repaired and can be used with an extremely low ambient temperature (

e.g

. -130℃).
