Effect of Iron Chloride Addition on Softwood Lignin Nano-Fiber Stabilization and Carbonization.

This study presents the effect of iron chloride addition on the production of nanocarbon fibers from softwood Organosolv lignin. It was shown that adding 2% FeCl to the lignin solution before electrospinning to produce lignin nanofibers increased the thermal resistance of lignin fibers during stabilization. FTIR and XPS analyses of the lignin fibers stabilized with and without FeCl revealed that the temperature rate could be increased in the presence of FeCl from 1 to 3 °C/min.
