Researchers investigated the effects of cellulose nanocrystals (CNC), modified with acryloyl chloride or a cationic surfactant (HDTMA), on  a bio-based nanocomposite UV-cured coating system based on he nonpolar polymer matrix (acrylated epoxidized soybean oil (AESO)). The tensile strength and modulus of elasticity (MOE) of the cured film coatings increased with the addition of CNC. Hardness, Er, MOE and tensile strength increased with CNC loading level in the matrix. Moreover, hardness measurements of cured film coating by pencil hardness test methods confirmed that CNC improved the hardness of the films.
