Cellulose synthase complex organization and cellulose microfibril structure [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017
Cellulose consists of linear chains of β-1,4-linked glucose units, which are synthesized by the cellulose synthase complex (CSC). In plants, these chains associate in an ordered manner to form the cellulose microfibrils. Both the CSC and the local environment in which the individual chains coalesce to form the cellulose microfibril ...

Inelastic behaviour of cellulose microfibril networks

Soft Matter, 2018
Weak physical interactions between cellulose microfibrils play an important role in shaping the nonlinear rheological behaviour of their networks.

Hydrogen bonds and twist in cellulose microfibrils [PDF]

Carbohydrate Polymers, 2017
There is increasing experimental and computational evidence that cellulose microfibrils can exist in a stable twisted form. In this study, atomistic molecular dynamics (MD) simulations are performed to investigate the importance of intrachain hydrogen bonds on the twist in cellulose microfibrils.

MECHANISM OF DISORDER GENESIS IN CELLULOSE MICROFIBRILS

Cellulose Chemistry and Technology, 2021
"We discuss the possible mechanism of genesis of disordered regions in cellulose microfibrils. In our work, we show that obstacles stopping the growth of nanofibrils and the further deformation of nanofibrils may be the reasons for disorder. In this case, the initial prismatic shape of nanofibrils becomes corrugated and regions, where cellulose chains ...

Behavior of the cellulose microfibril in shrinking woods [PDF]

Journal of Wood Science, 2006
We measured the longitudinal and tangential shrinking processes in wood specimens from Chamaecyparis obtuse Endl. with different microfibril angles (MFAs). The shape of the shrinking curve was compared with the MFA. Only the longitudinal shrinking process of specimens with a small MFA clearly showed nonlinearity, and the degree of nonlinearity ...

Structure and properties of the cellulose microfibril

Journal of Wood Science, 2009
The current structural models of the cellulose microfibril as well as its mechanical and thermal properties are reviewed. The cellulose microfibril can be considered as a single thin and long crystalline entity with highly anisotropic physical properties.

Properties of Polymer Composites with Cellulose Microfibrils [PDF]

, 2011
Polypropylene-based composites containing 10–30% by weight cellulose microfibrils were studied. Composites with polypropylene and cellulose microfibrils were characterised by MS-coupled simultaneous TGA-DSC and the reinforcing effect of cellulose microfibrils was emphasised by mechanical characterization.

Morphology and Crystallization of Polypropylene/Microfibrillated Cellulose Composites [PDF]

KMUTNB International Journal of Applied Science and Technology, 2014
Microfibrillated cellulose (MFC) was prepared by controlling the re-precipitation of cellulose prepared in the mixture form of NaOH/Urea solubilized microcrystalline cellulose (MCC) and starch. The cellulose re-precipitation was carried-out in an HCl bath, resulting in a MFC form having relatively lower crystallinity than MCC.

Multiscale structure of cellulose microfibrils in regenerated cellulose fibers

Carbohydrate Polymers
Cellulose in solution can be assembled into textile fibers by wet-spinning (Viscose etc.) or dry-jet wet spinning (Lyocell, Ioncell etc.), which leads to significant differences in the mechanical properties of fibers. We use scanning X-ray microdiffraction (SXM) to reveal regenerated fibers having a "skin-core" morphology.
