Fabrication and Characterization of Electrospun Poly(acrylonitrile--Methyl Acrylate)/Lignin Nanofibers: Effects of Lignin Type and Total Polymer Concentration.

Lignin macromolecules are potential precursor materials for producing electrospun nanofibers for composite applications. However, little is known about the effect of lignin type and blend ratios with synthetic polymers. This study analyzed blends of poly(acrylonitrile--methyl acrylate) (PAN-MA) with two types of commercially available lignin, low sulfonate (LSL) and alkali, kraft lignin (AL), in DMF solvent.
