TEMPO-oxidized cellulose nanofibers.
The new cellulose-based nanofibers formed by size reduction process of native cellulose fibers by TEMPO-mediated oxidation have potential application as environmentally friendly and new bio- based nanomaterials in high-tech fields. Expand
Cellulose nanofibers prepared by TEMPO-mediated oxidation of native cellulose.
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,Expand
Homogeneous suspensions of individualized microfibrils from TEMPO-catalyzed oxidation of native cellulose.
Never-dried native celluloses (bleached sulfite wood pulp, cotton, tunicin, and bacterial cellulose) were disintegrated into individual microfibrils after oxidation mediated by theExpand
TEMPO-mediated oxidation of native cellulose. The effect of oxidation conditions on chemical and crystal structures of the water-insoluble fractions.
Water retention values of cotton linter can be increased from 60% to about 280% through the introduction of hydrophilic carboxylate groups and morphological changes from fibrous forms to short fragments by the TEMPO-mediated oxidation. Expand
Transparent and high gas barrier films of cellulose nanofibers prepared by TEMPO-mediated oxidation.
The T OCN films prepared from softwood cellulose were transparent and flexible and had extremely low coefficients of thermal expansion caused by high crystallinity of TOCN, which is promising for potential applications in some high-tech materials. Expand
Individualization of nano-sized plant cellulose fibrils by direct surface carboxylation using TEMPO catalyst under neutral conditions.
Solid-state (13)C NMR and X-ray analyses revealed that the C6 carboxylate groups formed are selectively present on the crystalline fibril surfaces at high densities. Expand
An ultrastrong nanofibrillar biomaterial: the strength of single cellulose nanofibrils revealed via sonication-induced fragmentation.
The strength values estimated for the cellulose nanofibrils in the present study are comparable with those of commercially available multiwalled carbon nanotubes. Expand
Introduction of aldehyde groups on surfaces of native cellulose fibers by TEMPO-mediated oxidation
Abstract Native cellulose fibers were suspended in water and oxidized to various degrees with sodium hypochlorite and catalytic amounts of 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) andExpand
Preparation and characterization of TEMPO-oxidized cellulose nanofibril films with free carboxyl groups
Abstract A 2,2,6,6-tetramehylpiperidine-1-oxy radical (TEMPO)-oxidized wood cellulose with sodium carboxylate groups was completely converted to individual TEMPO-oxidized cellulose nanofibrils withExpand
