Structural Influence on Lignin Nanoparticle Fabrication and Its Functional Application

Lignin nanoparticles have drawn wide research attentions due to their structural diversity， renewability， and biodegradability. However， the morphology， size， stability， and surface chemistry properties of lignin nanoparticles are varied from raw materials spices and production processes. This paper summarized the recent research progress in preparing lignin nanoparticles with their properties and applications， mainly focusing on the influence of structural characteristics of lignin on nanoparticle morphology and functions. In addition， the applications of lignin nanoparticles in enhanced nanocomposites， UV shielding materials， biomedical materials， and food packaging are also discussed， providing new insights into lignin application in high-value-added bio-based materials.
