| Abstract:Composite modification of lignin and chitosan represents a crucial direction for the high-value utilization of biomass resources. This paper systematically reviewed efficient extraction technologies for lignin， with a focus on summarizing recent advances in the preparation techniques for lignin/chitosan composite materials. Composites were prepared by the methods such as solution blending， electrostatic compounding and self-assembly technology， which demonstratd unique advantages in applications including heavy metal ion adsorption， microcapsule-based controlled release systems， and biodegradable food packaging. Finally， this paper summarized the existing problems and challenges in the development and applications of such materials， providing theoretical guidance and practical references for optimizing the performance and expanding the functionalities of biomass-based composites. |
