DOI: 10.1177/155892501701200405
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… read more here.
