Nanoengineering the Redispersibility of Cellulose Nanocrystals

Biomacromolecules, 2022
Enhancing the redispersibility of dried colloidal particles to yield stable dispersions after rehydration is a persistent challenge in the sustainable processing of nanocelluloses due to hydrogen bonding-induced irreversible aggregation. Programming nanocelluloses, such as cellulose nanocrystals (CNC), with moieties that enable colloidal repulsion ...

Synthesis and conservation of cellulose nanocrystals

Carbohydrate Polymers, 2020
This work deals with the preparation of cellulose nanocrystals (CNC) from microcrystalline cellulose by acid hydrolysis, discusses how their characteristics varied according to the drying technique used for their conservation and analyzes their re-dispersion in water. A stable water dispersion of "rod" or "needle" type CNC (≈5 nm of diameter, 276 nm of

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.

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.

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.
