Vol.20 (2008), p. 4821–4825.10.1002/adma.200801008http://hdl.handle.net/10400.21/3626Helically 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.engCelluloseLiquid crystalsNanofibersElectrospinningHelicesChiralityModellingjournal article
