Description

The present chapter emphasizes the preparation of new nanocomposite coatings based on an acrylic polymeric matrix loaded with cellulose nanocrystals (CNCs). Solvent casting and convective assembly were used as processing methods to prepare, respectively, thick and thin coatings with various CNC loadings. Strong interactions between the polymeric matrix and CNCs were revealed, contributing to a significant improvement of the thermal stability and mechanical properties of both nanocomposite films. More importantly, shear-convective assembly was used herein to create nanostructured coatings of rod-like CNCs embedded in a protective hydrophobic polymer matrix. The possibility to control CNC alignments opens the door to these renewable building blocks in coating applications such as scratch-resistant, pigment-free coatings, security papers, and optical devices.
