  • Cellulose nanocrystal (CNC) films and conductive CNC-based polymer films produced using electrochemical techniques
    Patent number: 10081880
    Abstract: The present describes a chiral nematic cellulose nanocrystal (CNC) film comprising: cellulose nanocrystals that self-assemble to form an iridescent CNC structure, wherein the self-assembled structure comprises a finger-print pattern of repeating bright and dark regions, defining a pitch of the iridescent film, where the pitch variable. Also described are conductive polymer nanocomposite based on the CNC film. Further described is the electrophoretic method of producing the chiral nematic cellulose nanocrystal film as well as the polymer nanocomposites and the apparatus used.
