A review on lignin based nanocomposites: Fabrication, characterization and application

Abstract

Polymer Composite material is made of two or more constituent materials that, when combined, produce a material with properties that are distinct from those of the individual constituents. The fabrication of polymer nanocomposites especially lignin-based nanocomposites are growing prospective research interest, thanks to various advancements made possible by the combination of a polymeric matrix with, in most cases, an inorganic nonmaterial. The advancement and modification of lignin-based nanocomposites is a step towards the replacement of conventional plastics (traditional polymer). Polymer composites have been produced or formed specifically for a variety of applications that are employed in a specific location for a specific purpose. Lignin is a highly heterogeneous polymer that is found naturally in plants that account for up to 15–35% of woody biomass made up of several precursors. Lignols that crosslink in a variety of ways with antioxidant property, high thermal stability, biodegradability, and UV absorption characteristics. Despite the fact that lignin is the most prevalent phenolic component in nature, and a small percentage of lignin removed by industrial processing which gets turned into dispersants and fillers has the potential to enhance various properties like mechanical, thermal, thermo-chemical, anticorrosive, flame retardant and many more of the polymer composite which is beneficial for our society as well our environment.
