Bio-renewable precursor fibers from lignin/polylactide blends for conversion to carbon fibers

FABRICATION OF CARBON FIBERS FROM COMMERCIAL WET SPIN POLYACRYLONITRILE FIBERS

Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...

Bio-renewable fibers extracted from lignin/polylactide (PLA) blend

Due to the high cost and environment issues in the production of carbon fiber from polyacrylonitrile (PAN) and pitch, the use of low cost bio-renewable materials are of great interest as an alternative precursor. Lignin is a highly aromatic biopolymer, extracted as a byproduct of wood pulping and has been investigated as a suitable precursor for carbon fibers. In the present work, we have demon...

From Tilings to Fibers – Bio-mathematical Aspects of Fold Plasticity

Highly extensible bio-nanocomposite fibers.

Here, we show that a poly(ethylene oxide) polymer can be physically cross-linked with silicate nanoparticles (Laponite) to yield highly extensible, bio-nanocomposite fibers that, upon pulling, stretch to extreme lengths and crystallize polymer chains. We find that both, nanometer structures and mechanical properties of the fibers respond to mechanical deformation by exhibiting strain-induced cr...
