Nanocellulose, a nanoscale derivative from renewable biomass sources, possesses remarkable colloidal properties in water, mechanical strength, and biocompatibility. It emerges as a promising bio-based dispersing agent for various nanomaterials in water. This mini-review explores the interaction between cellulose nanomaterials (nanocrystals or nanofibers) and water, elucidating how this may enable their potential as an eco-friendly dispersing agent. We explore the potential of nanocellulose derived from top-down processes, nanocrystals, and nanofibers for dispersing carbon nanomaterials, semiconducting oxide nanoparticles, and other nanomaterials in water. We also highlight its advantages over traditional methods by not only effectively dispersing those nanomaterials but also potentially eliminating the need for further chemical treatments or supporting stabilizers. This not only preserves the exceptional properties of nanomaterials in aqueous dispersion, but may even lead to the emergence of novel hybrid functionalities. Overall, this mini-review underscores the remarkable versatility of nanocellulose as a green dispersing agent for a variety of nanomaterials, inspiring further research to expand its potential to other nanomaterials and applications.
纳米纤维素是一种源自可再生生物质资源的纳米级衍生物，在水中具有卓越的胶体性质、机械强度和生物相容性。它成为一种有前景的用于各种纳米材料在水中的生物基分散剂。这篇小型综述探讨了纤维素纳米材料（纳米晶体或纳米纤维）与水之间的相互作用，阐明了这如何使其具备作为环保型分散剂的潜力。我们探究了源自自上而下法的纳米纤维素、纳米晶体和纳米纤维在水中分散碳纳米材料、半导体氧化物纳米颗粒及其他纳米材料的潜力。我们还强调了它相对于传统方法的优势，即不仅能有效分散那些纳米材料，还可能无需进一步的化学处理或支撑稳定剂。这不仅保留了纳米材料在水性分散体中的优异性能，甚至可能带来新型杂化功能的出现。总体而言，这篇小型综述强调了纳米纤维素作为多种纳米材料的绿色分散剂具有非凡的多功能性，激发了进一步的研究以拓展其在其他纳米材料和应用方面的潜力。
