Journal ArticleDOI
Helicoidal self-ordering of cellulose microfibrils in aqueous suspension.
TL;DR: An in vitro system that attracts by its simplicity, where above a critical concentration the colloidal dispersion separates spontaneously into a chiral nematic liquid crystalline phase and solidifies into regularly twisted fibrillar layers that mimic the structural organization of helicoids in nature.
Journal ArticleDOI
Effect of microcrystallite preparation conditions on the formation of colloid crystals of cellulose
TL;DR: In this paper, the particle size of cellulose microcrystallites was characterized with transmission electron microscopy and photon correlation spectroscopy, and the surface charge was determined by conductometric titration.
Journal ArticleDOI
Chiral nematic suspensions of cellulose crystallites; phase separation and magnetic field orientation
TL;DR: The critical volume fraction for phase separation of salt-free suspensions is typically 0.03, with a relatively narrow biphasic region as discussed by the authors, and the ordered phase becomes oriented in a magnetic field with its chiral nematic axis parallel to the applied field.
Journal ArticleDOI
Enhanced Ordering of Liquid Crystalline Suspensions of Cellulose Microfibrils: A Small Angle Neutron Scattering Study
TL;DR: In this article, small angle neutron scattering (SANS) was used to characterize the enhanced ordering induced by magnetic and shear alignment of chiral nematic liquid crystals of cellulose microfibrils in aqueous suspension.
Solid self-assembled films of cellulose with chiral nematic order and optically variable properties
TL;DR: In this article, a film de cellulose se forme dans lequel les microcrystallites retiennent leur orientation nematique chirale, i.e., when on laisse evaporer dans l'eau des suspensions de ces microcrystites sur a surface plane, un film of cellulose forme.
