Cellulose Nanocrystals: Mind the Microgap in Iridescent Cellulose Nanocrystal Films (Adv. Mater. 2/2017)

Abstract

Cellulose nanocrystals are isolated from plant cellulose structures, e.g., cotton. In article 1603560, M. H. Godinho and co‐workers describe a tunable photonic material produced from these cellulose nanocrystals iridescent films, which reflects both right‐ and left‐handed circularly polarized light, taking advantage of the gaps existing along the cellulose nanocrystals films that are filled with a nematic liquid crystal.
