Abstract
Official abstract text for this publication.
A method of producing carbon fiber, yarns, and nonwoven carbon fiber cloths, includes forming suitable polymeric precursor microfibers and/or nanofibers using a centrifugal spinning process and decomposing at least a portion of the polymeric precursor fibers to form carbon fibers. The decomposition may be accomplished by treating the polymeric precursor fibers with acid vapor from an aqueous acid solution at a temperature of less than 250° C.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of producing activated carbon fibers and/or carbon fiber cloths, comprising: placing a polymer into a body of a fiber producing device, the body comprising one or more openings, wherein the polymer comprises a carbon backbone having hydroxyl (—OH) pendant groups; rotating the fiber producing device at a speed of at least about 500 rpm, wherein rotation of the fiber producing device causes the polymer in the body to be passed through one or more op…
