Helical Twisting of Electrospun Liquid Crystalline Cellulose Micro- and Nanofibers

Ver documento

Detalhes bibliográficos
Resumo:Helically twisted fibers can be produced by electrospinning liquid-crystalline cellulose solutions. Fiber topographies are studied by atomic force microscopy, scanning electron microscopy (see figure) and polarized optical microscopy. The fibers have a nearly universal pitch-to-diameter ratio and comprise both right- and left-handed helices.
