中文摘要:

      木质素作为可再生天然芳香性高分子生物质资源受到人们越来越多的关注，对木质素高值化利用的研究在不断深入。木质素纳米颗粒（LNP）的制备与应用是实现木质素高值化利用的有效途径，木质素具有环境和生物相容性好、价格低廉且资源丰富等优点，但其固有的异质性、颗粒尺寸较大和分散性差的问题阻碍其应用，木质素纳米化可实现颗粒尺寸大小和形态的可控，LNP的比表面积和表面功能位点增加，相比原始木质素，抗氧化、抗紫外线等能力得到进一步增强，具有广泛的应用前景。本文对LNP的制备以及在水凝胶材料中的应用进行了综述，并对未来发展进行了展望。

Abstract:

      Lignin as a renewable natural aromatic polymer and a biomass resource is receiving more and more attention， and the research on the high value utilization of lignin is in progress. The preparation and application of lignin nanoparticles （LNP） are an effective way to realize the high-value utilization of lignin. Lignin has the advantages of being good environmental and biocompatibility， low price and abundant ， but its inherent problems of heterogeneity， large particle size and poor dispersion hinder its high value application. Lignin nanosizing can control particle size and morphology， and increase the specific surface area and surface functional sites of LNP， and further enhance the antioxidant and UV resistance compared with the original lignin. Lignin nanosizing has a wide application prospect. In this paper， the preparation of LNP and its application in hydrogel materials were reviewed and the future development was anticipated.
