Abstract:
This invention describes development of a novel flexible film comprising nanocrystalline cellulose (NCC), or cellulose nanocrystals (CNC), and a controlled amount of a suitable zwitterionic (amphoteric) surfactant. The films are iridescent and have a high level of structural integrity, where mechanical properties can be engineered to suit the end applications. Flexible NCC films can be used in a multitude of applications, for instance, electrostatic shielding, gas barrier, hard coatings, printing.
