In article number 1802060 , Paul Russo, Elsa Reichmanis, Justin Zoppe, and co‐workers report a bio‐derived, temperature‐switchable liquid crystal developed via the patchy decoration of cellulose nanocrystals with a thermoresponsive polymer. Below the lower critical solution temperature of the polymer, the cellulose nanocrystals are in an ordered phase that exhibits birefringence; above the transition temperature, the polymer chains collapse and the cellulose nanocrystals lose their liquid crystal ordering.
