Synthesis of Lignin-Based Nanomaterials/Nanocomposites: Recent Trends and Future Perspectives

摘要

Lignin is a hetero biopolymer source of non-fossil carbon that is distinctively made up of phenyl propane entities. Its assortment of qualities geographically and wide applications attract biomass researchers worldwide. Lignin often exists as a glue in the plant cell walls in that it holds cellulose and hemicellulose together. Usually, the organization of lignin varies from one biomass species to another, and the structure of isolated lignin is affected by the method of extraction employed. In this review, we attempt to address the recently developed synthetic methodologies for producing lignin-based nanomaterials (i.e., nanoparticles, nanotubes, composites). The aim is to comprehend the chemistry of lignin-building design for its various practical uses. In the first part of this article, we focus on lignin biosynthesis. The challenges and future prospects of lignin-based nanomaterials synthesis are also discussed.
