dc.description.abstract Softwood Kraft lignin (SKL) and fractions obtained from solvent fractionation were used and characterized. Characterizations showed that F₄SKL, the solubilizable fraction with the highest molecular weight, exhibits association of the lignin molecules. A small amount of F₄SKL facilitated the dispersion of multi-walled carbon nanotubes (MWNTs) in dimethylformamide (DMF) solutions. π-interactions played an important role in the effective dispersal of MWNTs. Raman spectroscopy data also revealed that greater concentrations of F₄SKL could further disperse MWNTs. Also,dispersion of MWNTs affects the performance of the electrospinning process.The mechanical properties and electrical conductivity of the fibres did not improve with incorporating MWNTs. en_US
