Periodic Disorder along Ramie Cellulose Microfibrils

Biomacromolecules, 2003
Small angle neutron scattering studies have been carried out on cellulose fibers from ramie and Populus maximowicii (cotton wood). Labile hydrogen atoms were replaced by deuterium atoms, in water-accessible disordered regions of the fibers, to increase the neutron scattering contrast between the disordered and crystalline regions.

Exploring the Nature of Cellulose Microfibrils

Biomacromolecules, 2015
Ultrathin cellulose microfibril fractions were extracted from spruce wood powder using combined delignification, TEMPO-catalyzed oxidation, and sonication processes. Small-angle X-ray scattering of these microfibril fractions in a "dilute" aqueous suspension (concentration 0.077 wt %) revealed that their shape was in the form of nanostrip with 4 nm ...

Extensional viscosity of microfibrillated cellulose suspensions

Carbohydrate Polymers, 2014
The extensional properties of micro fibrillated cellulose (MFC)-suspensions at different fibril concentrations and with different amounts of added sodium chloride were evaluated. The MFC-suspensions were obtained by diluting a stock solution consisting of 0.95 wt.% cellulose with either deionized water or sodium chloride solution, giving a series of ...

Cellulose Microfibril Twist, Mechanics, and Implication for Cellulose Biosynthesis

The Journal of Physical Chemistry A, 2013
All-atom molecular dynamics simulations with explicit water solvent were used to investigate the microstructure and conformational dynamics of cellulose Iβ microfibrils as a function of microfibril length and cross-sectional size and shape. Cellulose microfibrils quickly develop a right-handed twist, which then remains stable over the entire 10 ns ...

Polymer composites with cellulose microfibrils

Polymer Engineering & Science, 2007
Abstract Polymer composites with cellulose microfibrils are materials with unique properties compared to existing materials: high strength, formability, and geometrical complexity at very small scale, low density, and abrasivity, biomedical compatibility, and possibility of recycling.

A native cellulose microfibril model

Cellulose, 1998
To aid in the understanding of cellulose ultrastructure, computer modelling has been employed to create a model of monoclinic (Iβ) native cellulose. This was achieved by building a chain of cellulose, which was used in a two chain unit cell. An energy minimized microfibril model was created from several of these unit cells.
