Reinforcing Poly(ethylene) with Cellulose Nanocrystals

Macromolecular Rapid Communications, 2014
The fabrication of nanocomposites of low‐density polyethylene (LDPE), one of the world's most widely used polymers, and cellulose nanocrystals (CNCs), which represent the world's most abundant bio‐based nanofiller, is reported. While the hydrophobic polymer and the hydrophilic filler seem to be intrinsically incompatible, this article shows that it is ...

Surfactant-enhanced cellulose nanocrystal Pickering emulsions

Journal of Colloid and Interface Science, 2015
The effect of surfactants on the properties of Pickering emulsions stabilized by cellulose nanocrystals (CNCs) was investigated. Electrophoretic mobility, interfacial tension, confocal microscopy and three-phase contact angle measurements were used to elucidate the interactions between anionic CNCs and cationic alkyl ammonium surfactants ...

Hybrid cellulose nanocrystal/magnetite glucose biosensors

Carbohydrate Polymers, 2020
There exists a high demand for simple and affordable blood glucose monitoring methods. For this purpose, new generations of biosensors are being developed for possible in vivo or dermal use. We present (non)sulphated cellulose nanocrystal/magnetite thin films to act as dermal and oral glucose biosensors.

Flow induced attrition of cellulose nanocrystals

Carbohydrate Polymers, 2023
To study the potential impacts of shear stress on cellulose nanocrystals (CNCs), a microcapillary rheometer was employed to repeatedly shear approximately 10 mL of 6 wt% aqueous CNC suspension at 25 °C and rates ranging from 1,000 s-1 to 501,000 s-1. A 9 wt% CNC suspension was also tested at 316,000 s-1 for comparison of concentration effects on the ...

Freeze–Thaw Gelation of Cellulose Nanocrystals

ACS Macro Letters, 2019
Gels are attractive for applications in drug delivery, tissue engineering, and 3D printing. Here, physical colloidal gels were prepared by freeze-thaw (FT) cycling of cellulose nanocrystal (CNC) suspensions. The aggregation of CNCs was driven by the physical confinement of CNCs between growing ice crystal domains. FT cycling was employed to form larger

Bacterial Cellulose Nanocrystals-Embedded Silk Nanofibers

Journal of Nanoscience and Nanotechnology, 2012
Nanofibrous Bacterial cellulose nanocrystals (BCNs)-embedded silk fibroin were successfully fabricated using electrospinning. The morphology, structure and mechanical properties of the silk fibroin nanofibers were investigated at various BCNs concentrations from 0 to 7 wt%.

Cellulose Nanocrystal Iridescence: A New Model

Langmuir, 2012
A homogeneous aqueous dispersion of cellulose nanocrystals (CNs) that is left to evaporate in a Petri dish self-organizes into smectic liquid crystals that are actually liquid multilamellar structures. As evaporation proceeds, the liquid multilamellar structures solidify to become a solid multilamellar film.

Individually Dispersed Wood-Based Cellulose Nanocrystals

ACS Applied Materials & Interfaces, 2016
Good dispersion of cellulose nanocrystals (CNCs) in the polymer matrix is one of the key factors to obtaining good properties in the resulting nanocomposites. However, the preparation of individually dispersed CNCs in solvents or in polymer matrices has been a challenge.
