Abstract

See full text

The present application discloses carbonaceous nano-fibrous materials developed by electrospinning mixtures of alkali lignin with a polymer at varied mass ratios. The present application also discloses processing of the lignin/polymer fibers via progressive heat treatments for stabilization, pre-carbonization and carbonization. The resulting carbon nanofibers maintain a uniform shape and have high specific surface area.
