摘　　要：光热转换是利用太阳能最直接的方式,随着可持续生物质资源的全面利用和纳米技术的不断发展,纳米生物质材料作为可再生资源在光热转换领域受到了越来越多的关注。木质素作为自然界中储量仅次于纤维素的天然高分子聚合物,具有优异的紫外吸收和光热转换能力。现阶段,木质素的利用程度仍然较低,而木质素纳米颗粒(LNP)的制备与应用是实现木质素高值化利用的有效途径。相比原始木质素,LNP的高比表面积和可调控的形态及尺寸使其抗氧化、抗紫外等性能得到了进一步增强。鉴于此,本文总结了制备LNP的技术方法,重点介绍了LNP在光热转换领域的应用现状,探讨了其在光热转换领域中的主要挑战和前景。Photothermal conversion is the most direct way to utilize solar energy.With the comprehensive utilization of sustainable biomass resources and the continuous development of nanotechnology,nano-biomass materials have received more and more attention in the field of photothermal conversion as a renewable resource.Lignin,as a natural polymer second only to cellulose in nature,has excellent ultraviolet absorption and photothermal conversion ability.At present,the utilization degree of lignin is still low,and the preparation and application of lignin nanoparticle(LNP)is an effective way to achieve high-value lignin utilization.Compared with the original lignin,the high specific surface area and tunable morphology and size of LNP further enhance its antioxidant and UV resistance properties.In view of this,this paper summarized preparation methods of LNP,and focused on the application status of LNP in the field of photothermal conversion.Finally,the main challenges and prospects in the field of photothermal conversion were discussed.
