Abstract Cellulose nanocrystals (CNCs) self-assemble in water suspensions into liquid crystalline assemblies. Here, we elucidate the microstructural changes associated with nonlinear deformations (2–9 wt%) CNC through rheological analysis, that was performed parallel coupled rheology—polarized light imaging. We show material parameters from Fourier-transform rheology and stress decomposition ar...

Multilayer films consisting of nanocellulose and nanochitin as oxygen barrier coatings a conventional petroleum-based moisture plastic the substrate have been widely studied for food packaging applications. A challenge with enabling recycling such hybrid multilayer materials is separating coating from substrate. In this work, we poly(ethylene terephthalate) (PET) model chitin nanowhiskers (ChNW...

The fabrication of cellulose-spider silk bio-nanocomposites comprised of cellulose nanocrystals (CNCs) and recombinant spider silk protein fused to a cellulose binding domain (CBD) is described. Silk-CBD successfully binds cellulose, and unlike recombinant silk alone, silk-CBD self-assembles into microfibrils even in the absence of CNCs. Silk-CBD-CNC composite sponges and films show changes in ...
