Cellulose Nanocrystal-Filled Carboxymethyl Cellulose Nanocomposites

Journal of Nanoscience and Nanotechnology, 2006
Polymer nanocomposites are one of the important application areas for nanotechnology. Naturally derived organic nanophase materials are of special interest in the case of polymer nanocomposites. Carboxymethyl cellulose is a polyelectrolyte derived from natural materials. It has been extensively studied as a hydrogel polymer.

Iridescent Cellulose Nanocrystal Films Modified with Hydroxypropyl Cellulose

Biomacromolecules, 2020
The 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.

Multifunctional Cellulosic Scaffolds from Modified Cellulose Nanocrystals

ACS Applied Materials & Interfaces, 2017
A 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.

Cellulose nanocrystals by acid vapour: towards more effortless isolation of cellulose nanocrystals

Faraday Discussions, 2017
Cellulose nanocrystals (CNCs) are topical in materials science but their full potential is yet to be fulfilled because of bottlenecks in the production: the process consumes huge amounts of water, recycling the strong acid catalyst is difficult, and purification steps are cumbersome, particularly with lengthy dialysis.

Thermoresponsive and Injectable Composite Hydrogels of Cellulose Nanocrystals and Pluronic F127.

ACS Applied Bio Materials, 2021
Thermoresponsive amphiphilic Pluronic F127 triblock copolymer solutions have been widely investigated in smart biomaterial applications due to the proximity of its critical gel temperature to human body temperature.

Photoluminescent and photochromic smart window from recycled polyester reinforced with cellulose nanocrystals.

Luminescence (Chichester, England Print), 2022
Smart windows with long-persistent phosphorescence, UV protection, high transparency, and high rigidity were developed by easily immobilizing varying ratios of lanthanide-activated aluminate phosphor nanoscale particles within a composite of recycled ...

Spin-Induced Organization of Cellulose Nanocrystals

Biomacromolecules, 2022
Cellulose 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.

Facile extraction of cellulose nanocrystals

Carbohydrate Polymers, 2019
A simple process for extracting cellulose nanocrystals (CNCs) is proposed that only uses high-pressure homogenization (HPH) controlling a process temperature. The proposed process was assessed and compared with normal production through acidic hydrolysis.

Antibody Immobilization on Sulfated Cellulose Nanocrystals

Biomacromolecules, 2023
Exploiting 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.

Cellulose Nanocrystals/Cellulose Core-in-Shell Nanocomposite Assemblies

Langmuir, 2009
We 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 ...
