In this special issue three important classes of stimuli-sensitive polymers are comprehensively described in reviews and progress reports: shape-memory polymers (SMPs), stimuli-responsive gels, and liquid crystalline elastomers (LCE).
Long-term functionality and stability of liquid crystalline elastomers need to be improved.
Quoted textsource-backed
In general the long-term functionality/stability of LCEs needs to be improved.
Incorporation of diazobenzene groups into liquid crystalline elastomers leads to photo-induced shape-changing materials because isomerization induces a liquid crystalline phase transition.

The incorporation of diazobenzene groups into LCE leads to photo-induced shape-changing materials, whereby the isomerization induces a liquid crystalline phase transition.
Liquid crystalline elastomers change shape when anisotropy of the liquid crystalline phase is lost and reverse the shape change on cooling when anisotropy is regained.
Quoted textsource-backed
If the anisotropy of the liquid crystalline phase gets lost, e.g. because it is heated into the isotropic phase, a shape change of the LCE occurs, which is reversed on cooling when the anisotropic phase is regained.
