Abstract: The properties of carbonized lignin nanoparticles were investigated to determine if this material could be used as an environmentally-friendly alternative to carbon black. The observed surface area of the carbonized lignin was found to be higher than that of carbon black because the powder is highly porous. The lignin nanoparticles were able to be produced in such a way as to give a similar size as carbon black nanoparticles, with a similar carbon purity. The thermal conductivity of carbonized lignin nanoparticles was found to be higher than that of carbon black; however, the electrical conductivity was significantly reduced. These results led to the authors concluding that carbonized lignin nanoparticles could potentially be used as an alternative to carbon black in all applications excluding those requiring an electrically conductive material.
