Superabsorbent hydrogels (SAH) are crosslinked three-dimensional networks distinguished by their super capacity to stabilize a large quantity of water without dissolving. Such behavior enables them to engage in various applications. Cellulose and its derived nanocellulose can become SAHs as an appealing, versatile, and sustainable platform because of abundance, biodegradability, and renewability compared to petroleum-based materials. In this review, a synthetic strategy that reflects starting cellulosic resources to their associated synthons, crosslinking types, and synthetic controlling factors was highlighted. Representative examples of cellulose and nanocellulose SAH and an in-depth discussion of structure-absorption relationships were listed. Finally, various applications of cellulose and nanocellulose SAH, challenges and existing problems, and proposed future research pathways were listed.
高吸水性水凝胶（SAH）是交联的三维网络，其特点是能够稳定大量的水而不溶解。这种特性使它们能够应用于各种领域。与基于石油的材料相比，纤维素及其衍生的纳米纤维素由于丰富、可生物降解和可再生性，可成为具有吸引力、多功能和可持续性的平台，成为 SAH。在这篇综述中，突出了从起始纤维素资源到其相关单体、交联类型和合成控制因素的合成策略。列出了纤维素和纳米纤维素 SAH 的代表性实例，并深入讨论了结构-吸收关系。最后，列出了纤维素和纳米纤维素 SAH 的各种应用、挑战和存在的问题以及未来的研究途径。
