Abstract

Alkali lignin was subjected to a solid state percarbonate oxidation process for the development of a new nanostructured material to be used in advanced technologies. In this study, preliminary physical-chemical characterizations are reported. In particular GPC analysis showed an increase of molecular weight distribution after the percarbonate treatments, quantitative31P NMR, used to determine the structural modifications induced in the lignin structures, highlighted an increase in phenolic OH groups. Finally, SEM showed the formation of lignin nanosubstructures with a well defined diameter, length and porosity.
