dc.description.abstract Biobased poly(ethylene terephthalate) has been successfully blended with isopropyl alcohol fractioned hardwood organosolv lignin. The blend compatibility was analysed using Gibbs free energy calculation and confirmed by glass transition temperature measurements as well as morphological study. The obtained carbon fibres from this blend displayed a turbostratic carbon phase and their morphology exhibits a one phase smooth surface. The carbon yield of the blend was found to be improved by fractionation reaching values of ~ 40%. The chemical structure of lignin, most notably the amount of available aromatic hydroxyl groups, was critical for the success of this work. The high molecular weight fraction is enriched with aromatic hydroxyl groups that can crosslink as ether type bonds such as β-O-4 and β-5 bonds. When substituted to aliphatic hydroxyls in a modified lignin, the blend with BPET was found to be incompatible and produced a carbon fibre exhibiting two phases, low carbon yield and a low amount of turbostratic phase. en_US
