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
Atomic force microscopy of cellulose microfibrils: comparison with transmission electron microscopy
TL;DR: In this paper, atomic force microscopy images of the surface of the highly crystalline cellulose microfibrils were obtained at atomic resolution under ambient conditions; the images showed periodicities along the micro-fibril axis of 1.07 and 0.53 nm that may correspond to the fibre and glucose unit repeat distances.
Journal ArticleDOI
Electron microscopic evidence for cholesteric structure in films of cellulose and cellulose acetate
Journal ArticleDOI
Preparation of chiral nematic gels by radiation cross-linking
TL;DR: In this article, the crosslinking of (hydroxypropyl) cellulose liquid crystalline phases by exposure to gamma radiation is described and it is shown that the chiral nematic structure is at least partially retained after cross-linking, swelling and drying.
