摘要

摘要高吸水性聚合物(SAP)和改性天然聚合物水凝胶在农业、医疗保健纺织品、污水处理、药物输送、组织工程、民用混凝土结构等领域有着广泛而日益广泛的应用。然而,对这类新型聚合物的综述并不多。涵盖SAP所有可行应用的综述将对研究人员、行业人士以及医疗、保健和农业用途非常有用。因此,人们试图从SAP的分类、合成、交联改性和物理化学表征(如形态、溶胀性、热和机械性能、寿命预测、溶胀热力学、吸收、释放和传输动力学、亲水基团的定量等)来综述SAP。此外,还讨论了微调其结构以提高其吸收能力、快速吸收动力学、机械强度、控释特性等的可能方法,以扩大其用途。这篇综述还强调了SAP的生物降解性、商业可行性和市场潜力、SAP复合材料、使用生物质作为SAP生产原料的可行性等。还讨论了SAP的挑战和未来前景、其安全性和环境问题。

Superabsorbent polymers: a state-of-art review on their classification, synthesis, physicochemical properties, and applications
Abstract Superabsorbent polymers (SAP) and modified natural polymer hydrogels are widely and increasingly used in agriculture, health care textiles, effluent treatment, drug delivery, tissue engineering, civil concrete structure, etc. However, not many comprehensive reviews are available on this class of novel polymers. A review covering all the viable applications of SAP will be highly useful for researchers, industry persons, and medical, healthcare, and agricultural purposes. Hence, an attempt has been made to review SAPs with reference to their classifications, synthesis, modification by crosslinking, and physicochemical characterization such as morphology, swellability, thermal and mechanical properties, lifetime prediction, thermodynamics of swelling, absorption, release and transport kinetics, quantification of hydrophilic groups, etc. Besides, the possible methods of fine-tuning their structures for improving their absorption capacity, fast absorption kinetics, mechanical strength, controlled release features, etc. were also addressed to widen their uses. This review has also highlighted the biodegradability, commercial viability and market potential of SAPs, SAP composites, the feasibility of using biomass as raw materials for SAP production, etc. The challenges and future prospects of SAP, their safety, and environmental issues are also discussed.

期刊介绍: Reviews in Chemical Engineering publishes authoritative review articles on all aspects of the broad field of chemical engineering and applied chemistry. Its aim is to develop new insights and understanding and to promote interest and research activity in chemical engineering, as well as the application of new developments in these areas. The bimonthly journal publishes peer-reviewed articles by leading chemical engineers, applied scientists and mathematicians. The broad interest today in solutions through chemistry to some of the world’s most challenging problems ensures that Reviews in Chemical Engineering will play a significant role in the growth of the field as a whole.
