Cellulose Nanocrystal Submonolayers by Spin Coating
Langmuir, 2007Dilute concentrations of cellulose nanocrystal solutions were spin coated onto different substrates to investigate the effect of the substrate on the nanocrystal submonolayers. Three substrates were probed: silica, titania, and amorphous cellulose. According to atomic force microscopy (AFM) images, anionic cellulose nanocrystals formed small aggregates

Iridescent Cellulose Nanocrystal Films Modified with Hydroxypropyl Cellulose
Biomacromolecules, 2020The introduction of polymers into a chiral nematic cellulose nanocrystal (CNC) matrix allows for the tuning of optical and mechanical properties, enabling the development of responsive photonic materials. In this study, we explored the incorporation of hydroxypropyl cellulose (HPC) into a CNC film prepared by slow evaporation.

Spin-Induced Organization of Cellulose Nanocrystals
Biomacromolecules, 2022Cellulose nanocrystals (CNCs) are composed of chiral cellulose units, which form chiral nematic liquid crystals in water that, upon drying, self-assemble to more complex spiral chiral sheets. This secondary structure arrangement is found to change with an external magnetic or electric field.

Antibody Immobilization on Sulfated Cellulose Nanocrystals
Biomacromolecules, 2023Exploiting cellulose nanocrystals' high aspect ratio and tailorable surface for immunological biosensors has been hindered by the relatively limited research on using commonly available sulfated cellulose nanocrystals (CNCs) for antibody immobilization and by the low hydrolytic stability of dried assemblies produced from sulfated CNCs.

Multifunctional Cellulosic Scaffolds from Modified Cellulose Nanocrystals
ACS Applied Materials & Interfaces, 2017A biobased cellulosic scaffold material was made through freeze-drying ice-templating of functionalized cellulosic nanomaterials. The resulting interconnected highly porous scaffold was primarily composed of highly esterified, strong network of ultrathin cellulosic layers.

Polyhydroxybutyrate-Based Nanocomposites with Cellulose Nanocrystals and Bacterial Cellulose
Journal of Polymers and the Environment, 2016Polyhydroxybutyrate (PHB) films nanoreinforced with hydrolyzed cellulose nanocrystals (CNC) and bacterial cellulose (BC) were prepared by solvent casting. The influence of different cellulose nanoparticles content (2, 4 and 6 wt% of CNC and 2 wt% of BC) on the PHB properties was studied. CNC nanocomposites presented good dispersion of the nanocrystals,

Cellulose Nanocrystals/Cellulose Core-in-Shell Nanocomposite Assemblies
Langmuir, 2009We report herein for the first time how a co-electrospinning technique can be used to overcome the issue of orienting cellulose nanocrystals within a neat cellulose matrix. A home-built co-electrospinning apparatus was fabricated that was comprised of a high-voltage power supply, two concentric capillary needles, and one screw-type pump syringe ...
