Preparation of cellulose nanocrystals and carboxylated cellulose nanocrystals from borer powder of bamboo

Cellulose, 2014
Carboxylated cellulose nanocrystals (CCN) and cellulose nanocrystals (CNC) were prepared from borer powder of bamboo by two different kinds of procedures: one-step approach with ammonium persulfate for CCN and two-step approach with sulfuric acid for CNC.

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 ...

Polyhydroxybutyrate-Based Nanocomposites with Cellulose Nanocrystals and Bacterial Cellulose

Journal of Polymers and the Environment, 2016
Polyhydroxybutyrate (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, 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 ...

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.

A review of cellulose nanocrystals and nanocomposites

TAPPI Journal, 2011
Aqueous suspensions of cellulose nanocrystals can be obtained by acid hydrolysis of lignocellulosic fibers. Cellulose nanocrystals correspond to defect-free rod-like nanoparticles that present remarkable properties such as light weight, low cost, availability of raw material, renewability, nanoscale dimension, and unique morphology.

Functionalization of cellulose nanocrystals for advanced applications

Journal of Colloid and Interface Science, 2017
Replacing the widespread use of petroleum-derived non-biodegradable materials with green and sustainable materials is a pressing challenge that is gaining increasing attention by the scientific community. One such system is cellulose nanocrystal (CNC) derived from acid hydrolysis of cellulosic materials, such as plants, tunicates and agriculture ...

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

Cellulose Nanocrystals in Food Packaging

2019
Food packaging has become more demanding in order to offer the consumer good quality foods with high standards such as material performance and extended shelf life. Developments such as smart packaging that could bring active compounds, outstanding gas/vapor barrier properties, and also biodegradability to reduce plastic waste disposal represent an ...
