Significant progress in lignins valorization and development of high-performance sustainable materials have been achieved in recent years. Reports related to lignin utilization indicate excellent prospects considering green chemistry, chemical engineering, energy, materials and polymer science, physical chemistry, biochemistry, among others. To fully realize such potential, one of the most promising routes involves lignin uses in nanocomposites and nanohybrid assemblies, where synergistic interactions are highly beneficial. This review first discusses the interfacial assembly of lignins with polysaccharides, proteins and other biopolymers, for instance, in the synthesis of nanocomposites. To give a wide perspective, we consider the subject of hybridization with metal and metal oxide nanoparticles, as well as uses as precursor of carbon materials and the assembly with other biobased nanoparticles, for instance to form nanohybrids. We provide cues to understand the fundamental aspects related to lignins, their self-assembly and supramolecular organization, all of which are critical in nanocomposites and nanohybrids. We highlight the possibilities of lignin in the fields of flame retardancy, food packaging, plant protection, electroactive materials, energy storage and health sciences. The most recent outcomes are evaluated given the importance of lignin extraction, within established and emerging biorefineries. We consider the benefit of lignin compared to synthetic counterparts. Bridging the gap between fundamental and application-driven research, this account offers critical insights as far as the potential of lignin as one of the frontrunners in the uptake of bioeconomy concepts and its application in value-added products.

多功能木质素基纳米复合材料和纳米杂化物

近年来，木质素的增值和高性能可持续材料的开发取得了重大进展。考虑到绿色化学、化学工程、能源、材料和聚合物科学、物理化学、生物化学等，与木质素利用相关的报告表明了良好的前景。为了充分发挥这种潜力，最有希望的途径之一涉及木质素在纳米复合材料和纳米混合组件中的应用，其中协同相互作用非常有益。本综述首先讨论了木质素与多糖、蛋白质和其他生物聚合物的界面组装，例如在纳米复合材料的合成中。为了提供更广阔的视角，我们考虑了与金属和金属氧化物纳米颗粒的杂化，以及作为碳材料的前体的用途以及与其他生物基纳米颗粒的组装，例如形成纳米杂化物。我们提供线索来了解与木质素、其自组装和超分子组织相关的基本方面，所有这些对于纳米复合材料和纳米杂化物都至关重要。我们强调木质素在阻燃、食品包装、植物保护、电活性材料、能源存储和健康科学领域的可能性。鉴于木质素提取在现有和新兴生物精炼厂中的重要性，对最新结果进行了评估。我们考虑木质素与合成木质素相比的优势。该报告弥合了基础研究和应用驱动研究之间的差距，就木质素作为生物经济概念的采用及其在增值产品中的应用的领跑者之一的潜力提供了重要的见解。
