Abstract

In this study, a sulfur-free softwood lignin (SFSL) was electrospun to form bead-free fibers. The fibers were evaluated as potential precursors for carbon fiber production. Higher heating rates of thermostabilization caused afused fiber morphology. The lignin purification process also affected the quality of the SFSL-based carbon fibers. Therefore, the yield, morphological characteristics, structural characteristics, electrical conductivity and mechanical properties of the carbon fibers were evaluated. At higher carbonization temperatures crystalline carbon fibers were formed. As a result, as the carbonization temperature increased, the conductivity of SFSL-based carbon fibers also increased.
