Lignin is a vastly underutilized biomass resource. The preparation of water-dispersed lignin nanoparticles is an effective way to realize the high-value utilization of lignin. However, the currently reported preparation methods of lignin nanoparticles still have some drawbacks, such as the requirement for toxic organic solvent or chemical modification, complicated operation process, and poor dispersibility. Here, lignin/sodium dodecyl sulfate (SDS) composite nanoparticles (LSNPs) with outstanding water dispersibility and a size range of 70–200 nm were facilely prepared via acidifying the mixed basic solution of alkaline lignin and SDS. No harsh chemical was needed. The formation mechanism was systematically studied. Results indicated that the LSNPs were obtained by acid precipitation of the mixed micelles formed by the self-assembly of lignin and SDS. In addition, on the basis of the LSNP-stabilized Pickering emulsions, lignin/polyurea composite microcapsules combining the excellent chemical stability of a synthetic polyurea shell with the fantastic antiphotolysis and antioxidant properties of lignin were successfully prepared.

木质素/十二烷基硫酸钠复合纳米粒子的制备及其在基于Pickering乳液模板的微囊化中的应用
木质素是一种未被充分利用的生物质资源。制备木质素水分散纳米粒是实现木质素高价值利用的有效途径。然而，目前报道的木质素纳米颗粒的制备方法仍然存在一些缺点，例如需要有毒的有机溶剂或化学改性，操作过程复杂，分散性差。在此，通过酸化碱性木质素和SDS的混合碱性溶液，可以轻松制备木质素/十二烷基硫酸钠（SDS）复合纳米颗粒（LSNP），其具有出色的水分散性和70-200 nm的尺寸范围。不需要苛刻的化学药品。对形成机理进行了系统的研究。结果表明，LSNPs是由木质素和SDS的自组装形成的混合胶束的酸沉淀而获得的。另外，在LSNP稳定的Pickering乳液的基础上，成功制备了木质素/聚脲复合微囊，该微囊将合成的聚脲壳的优异化学稳定性与木质素的出色的抗光解性和抗氧化性相结合。
