Cellulose nanocrystals (CNCs) have received significant attention in academia and industry in recent years as reinforcement nano-fillers in polymer nanocomposites due to their exceptional properties, such high aspect ratio, large specific surface area, low density, high crystallinity, high tensile strength, and high elastic modulus. Polyamide 6 (PA6) nanocomposites containing cellulose nanocrystals (CNCs) were prepared via in-situ anionic ring-opening polymerization. The amine functionalized CNC showed improved dispersion and better mechanical and thermal properties in PA6 nanocomposites relative to unmodified CNC PA6 composites. The CNC surface modification was assessed through spectroscopic techniques including x-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR).
