| 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. This work was supported by the Portuguese Science Foundation (FCT) through Projects POCI/CTM/56382/2004 and POCTI/CTM/38330/2001, and through Pluriannual contracts with CENIMAT/I3N and ICEMS; and by the GRICES/Treaty of Windsor Programme through grant no. B-20/08. J. P. Canejo gratefully acknowledges FCT for grant SFRH/BD/37958/2007. |
