Abstract

Superabsorbent polymers (SAPs) are three-dimensional crosslinked hydrophilic polymers, that can absorb and retain liquids up to hundreds of times their weight. These polymers have diverse applications across various fields, including agriculture, biomedicine, separation technologies, and wastewater treatment. Among these cellulose-based SAPs are prominent due to their biodegradable nature, sustainability, biocompatibility, cost-effectiveness, and natural abundance. The development of SAPs has evolved significantly since 1961, marked by advancements in polymerization techniques and their integration into numerous aspects of daily life. This review provides a comprehensive analysis of recent advancements in the field of cellulose-based superabsorbents, focusing on their polymerization methods, source of cellulose, and diverse applications. Furthermore, it highlights the mechanisms by which different forms of cellulose can enhance liquid absorption capacity and kinetics across various applications. The findings underscore the importance of cellulose-derived SAPs in promoting environmentally sustainable practices while addressing the growing demand for effective water retention solutions in agricultural and industrial contexts.

纤维素基高吸水性聚合物的研究进展

高吸水性聚合物（sap）是一种三维交联亲水性聚合物，可以吸收和保留重量达自身重量数百倍的液体。这些聚合物在各个领域都有不同的应用，包括农业、生物医学、分离技术和废水处理。在这些基于纤维素的sap中，由于其可生物降解性，可持续性，生物相容性，成本效益和天然丰度而突出。自1961年以来，sap的发展发生了重大变化，其标志是聚合技术的进步及其融入日常生活的许多方面。本文综述了近年来纤维素基高吸水性材料的研究进展，重点介绍了纤维素基高吸水性材料的聚合方法、来源及其应用。此外，它强调了不同形式的纤维素在各种应用中增强液体吸收能力和动力学的机制。研究结果强调了纤维素衍生的sap在促进环境可持续实践方面的重要性，同时解决了农业和工业环境中对有效保水解决方案日益增长的需求。

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
