摘要:木质素中空纳米球是一种具有球形和独特中空结构的纳米颗粒，具有高的比表面积、生物相容性和高负载能力等特点，在生物医学、紫外防护、新能源等领域具有广阔的应用前景。本文针对自组装制备木质素中空纳米球的过程进行剖析，总结了近年来国内外溶剂-反溶剂法、界面细乳聚合法、模板法和交联/偶联聚合法等自组装方法制备纳米颗粒的形成过程与机理，以期对开发简单可控的自组装方法制备木质素中空纳米球、高效资源化应用提供借鉴。

Abstract:Lignin hollow nanospheres are a kind of nanoparticles with spherical and unique hollow structure， which have high specific surface area， biocompatibility and high loading capacity. They have broad application prospects in biomedicine， UV protection， new energy and other fields. In this paper， the self-assembly process of lignin hollow nanospheres was analyzed， and the forming process and preparation mechanism of self-assembly methods， such as solvent-anti solvent method， interfacial fine emulsion polymerization method， template method and cross-linking/coupling polymerization method， developed at home and abroad in recent years were summarized， in order to provide reference for the development of simple and controllable self-assembly preparation of lignin hollow nanospheres and efficient resource utilization.
