Cellulose nanocrystal-coated TEMPO-oxidized cellulose nanofiber films for high performance all-cellulose nanocomposites

Journal of Hazardous Materials, 2020
High performance biopolymer films are of great interest as effective alternatives to non-biodegradable and petroleum-based polymer films. However, most natural biopolymer films possess weak mechanical and poor gas barrier properties, limiting their applicability.

Biodegradation studies on periodate oxidized cellulose

Biomaterials, 1982
Abstract Sodium periodate oxidized cellulose was found to degrade into small molecules when implanted subcutaneously in rats. Thus the potentiality of using oxidized cellulose as a biodegradable drug carrier is envisaged.

Irradiation of Cellulosic Pulps: Understanding Its Impact on Cellulose Oxidation

Biomacromolecules, 2012
Different pulp samples were irradiated by three energy sources: plasma, electron beaming, and γ radiation. The effect of increased exposure to irradiation was studied by multidetector gel permeation chromatography with fluorescence labeling of carbonyl groups to quantify changes of the cellulose.

Cellulose Nanofibers Prepared by TEMPO-Mediated Oxidation of Native Cellulose

Biomacromolecules, 2007
Never-dried and once-dried hardwood celluloses were oxidized by a 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated system, and highly crystalline and individualized cellulose nanofibers, dispersed in water, were prepared by mechanical treatment of the oxidized cellulose/water slurries.

Micromechanics of TEMPO-Oxidized Fibrillated Cellulose Composites

ACS Applied Materials & Interfaces, 2012
Composites of poly(lactic) acid (PLA) reinforced with TEMPO-oxidized fibrillated cellulose (TOFC) were prepared to 15, 20, 25, and 30% fiber weight fractions. To aid dispersion and to improve stress transfer, we acetylated the TOFC prior to the fabrication of TOFC-PLA composite films.

OXIDIZED CELLULOSE—ABSORBABLE GAUZE

Journal of the American Medical Association, 1945
Dry gauze used to stanch bleeding in the open wound has, in the experience of most surgeons, been both life saving and hazardous. Hemorrhage has been checked which might otherwise have proved fatal, but the subsequent removal of the gauze which stuck to the raw surfaces often resulted in fresh bleeding, and the danger of infection was great.

Modification of carboxymethyl cellulose through oxidation

Carbohydrate Polymers, 2012
The periodate oxidation reaction of carboxymethyl cellulose involve the primary and secondary hydroxyl groups of the pyranose ring. The reaction is accompanied by the opening of the pyranose ring and resulting product is dialdehyde carboxymethyl cellulose along with some hydrated forms.

Molecular Mass and Molecular-Mass Distribution of TEMPO-Oxidized Celluloses and TEMPO-Oxidized Cellulose Nanofibrils

Biomacromolecules, 2015
Native wood cellulose was oxidized by 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-mediated oxidation, and the fibrous TEMPO-oxidized celluloses (TOCs) thus obtained were disintegrated in water to prepare TOC nanofibrils (TOCNs). The carboxyl groups of TOCs and TOCNs were methyl-esterified, and the methylated samples were dissolved in 8% LiCl/N,N ...

Oxidation Products of Cellulose. Salts of Oxidation Products of Cellulose

1995
The first spectra of a number of oxidized celluloses were obtained by Rowen, Hunt, and Plyler [164]. They used films of regenerated cellulose, oxidized by nitrogen dioxide or periodic acid. These authors erroneously attributed bands at 1640 and 1280 cm−1, in the spectrum of cellulose oxidized by nitrogen dioxide, to the carboxyl group.
