Summary

In the scientific world, “bionanocomposite” has become a common term to designate those polymeric materials involving a biopolymer, produced from plants or microorganisms or by other biological processes, reinforced with inorganic/organic fillers showing at least one dimension on the nanometer scale. Lignin is primarily burnt as a fuel for energy; however, as a part of the biorefinery concept, value‐added utilization of lignin is critical. Usually, the lignins used in preparation of blends or composites were produced industrially and obtained as a purified commercial polymer. Biobased nanocomposites containing lignin were prepared from organosolv lignins (OSL)/organoclay mixtures by mechanical mixing and subsequent melt intercalation. Recently, thermoplastics with high lignin content have been produced by alkylated kraft lignins (KRL) or blending KRL with synthetic polymers. Besides polyurethanes and polyesters, phenolic and epoxy resins are the most prominent applications of technical lignins in thermosetting materials.
