Presently, the rapid depletion of resources and drastic climate change highlight the importance of sustainable development. In this case, nanochitin derived from chitin, the second most abundant renewable polymer in the world, possesses numerous advantages, including toughness, easy processability and biodegradability. Furthermore, it exhibits better dispersibility in various solvents and higher reactivity than chitin owing to its increased surface area to volume ratio. Additionally, it is the only natural polysaccharide that contains nitrogen. Therefore, it is valuable to further develop this innovative technology. This review summarizes the recent developments in nanochitin and specifically identifies sustainable strategies for its preparation. Additionally, the different biomass sources that can be exploited for the extraction of nanochitin are highlighted. More importantly, the life cycle assessment of nanochitin preparation is discussed, followed by its applications in advanced manufacturing and perspectives on the valorization of chitin waste.
目前，资源的快速枯竭和剧烈的气候变化凸显了可持续发展的重要性。在这种情况下，由几丁质衍生而来的纳米几丁质是世界上第二丰富的可再生聚合物，具有许多优点，包括韧性、易于加工性和生物降解性。此外，由于其表面积与体积比增加，它在各种溶剂中表现出更好的分散性，并且比几丁质具有更高的反应活性。此外，它是唯一含氮的天然多糖。因此，进一步发展这项创新技术具有重要价值。本综述总结了纳米几丁质的最新进展，并特别确定了其制备的可持续策略。此外，还强调了可用于提取纳米几丁质的不同生物质来源。更重要的是，讨论了纳米几丁质制备的生命周期评估，随后介绍了其在先进制造中的应用以及几丁质废料增值的前景。
