Abstract:
Poly-(caffeyl alcohol) (PCFA), also known as C-lignin, is a promising new source of both carbon fibers and pure carbon. PCFA can be used to produce carbon fibers by direct electrospinning, without blending with another polymer to reduce breakage. Analyses have shown that the carbon obtained from PCFA is superior to that obtained from other lignins. The fibers formed from PCFA are smoother, have a narrower diameter distribution, and show very low defects. The PCFA can be obtained by extraction from plant seed coats. Examples of these plants include the  vanilla  orchid,  Vanilla planifolia,  and  Jatropha curcas.  The fibers may be formed through electrospinning, although other methods for forming the fibers, such as extrusion with a carrier polymer, could be used. The fibers may then be carbonized to increase the carbon yield.

Claim (Index 1):
Carbon fibers, consisting of:\n 100 wt. % PCFA, wherein the carbon fibers are produced by extracting poly-(caffeyl alcohol) (PCFA) from a plant to produce extracted PCFA and electrospinning the extracted PCFA to produce the carbon fibers.
