Lignin electrospinning

Nettet17. mai 2024 · Standard electrospinning was performed using a solution of 45.5 wt% lignin in DMF. A blunt 21G needle was employed with a tip-to-collector distance of 15 cm to a metal plate to collect the fibers as a non-woven mat. A voltage of 23.0 kV was used at a flow rate of 0.3 ml/h, with a total volume of 1 ml solution. Nettet1. des. 2024 · 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.
