Temperature Regulating Evaporation‐Induced Self‐Assembly of Chiral Nematic Cellulose Nanocrystals for Rational Design of Iridescent Films
Cellulose nanocrystals (CNCs) are one of the promising bio‐based nanomaterials with a distinctive chiral nematic structure for fabricating optically iridescent films, yet their long evaporation time for self‐assembly and poor flexibility greatly inhibit practical applications. Herein, pure CNCs and modified CNCs film...
