| Abstract:Lignin， as the most abundant renewable aromatic polymer， has significant potential in the field of green materials due to its phenylpropane structure and biodegradability. This review focused on the molecular structure， material classification， preparation techniques， and functional modification of lignin， summarizing the research progress in lignin-based degradable materials. Lignin-based degradable materials were mainly categorized into three types： physically blended composites， chemically modified functional materials， and nanostructured materials. By physically blending lignin with natural or synthetic polymers， the mechanical properties and thermal stability of the materials were effectively enhanced. Chemical modification of its active sites enabled the targeted introduction of specific functionalities， such as antibacterial and UV-blocking properties. Furthermore， lignin nanoparticles constructed via nanotechnology demonstrated unique advantages in reinforcement， shielding， and drug delivery applications. |
