As a new product of high-value utilization of lignin, lignin micro/nano particles (LMNPs) have attracted the attention of researchers due to their non-toxicity, corrosion-resistance, UV resistance, and other excellent characteristics and potential application value. This article outlined the main preparation methods of LMNPs at the current stage, summarized and compared them from three perspectives of preparation technology, final product state and product composition. Subsequently, based on the different focuses of the properties of LMNPs, their application research progress as fillers, UV blockers, drug delivery carriers, among others, were introduced. Then a concise analysis of the technical and economic assessment and life cycle assessment of LMNPs in the process of industrialization was made. Finally, the main problems at present and the future development directions were analyzed and prospected to provide references for the deep processing of forest resources and the development of bio-based nanomaterials.
作为木质素高值化利用的新产品，木质素微/纳米颗粒（LMNPs）因其无毒、耐腐蚀、耐紫外线等优异特性和潜在应用价值而引起了研究人员的关注。本文概述了现阶段 LMNPs 的主要制备方法，从制备技术、最终产品状态和产品组成三个方面对其进行了总结和比较。随后，基于 LMNPs 性能的不同侧重点，介绍了其作为填充剂、紫外线阻隔剂、药物载体等方面的应用研究进展。然后对 LMNPs 在工业化过程中的技术经济评估和生命周期评估进行了简要分析。最后，分析了目前存在的主要问题和未来的发展方向，为森林资源的深加工和生物基纳米材料的发展提供了参考。
