Abstract
A method of large-scale continuous roll-to-roll fabrication of cellulose nanocrystal (CNC) coatings with controlled anisotropy, and CNC-coated flexible substrates prepared thereby. An order parameter of 0.78 is observed in CNC-poly(vinyl alcohol) (CNC-PVA) coating systems at 70% CNC loadings.
Claims11
A cellulose nanocrystal-coated flexible substrate comprising a flexible substrate and at least one cellulose nanocrystal layer that is anisotropic and has an order parameter of at least 0.2.
A cellulose nanocrystal-coated flexible substrate comprising a cellulose nanocrystal-containing coating on a flexible substrate, wherein the cellulose nanocrystal-containing coating is anisotropic and has an order parameter of 0.6 to 0.95.
