Classification and Synthesis of Highly Absorbent Resins and Their Research Progress in Different Fields in Recent Years
Super absorbent resins(SARs)have a unique three-dimensional cross-linked internal mesh structure that can both absorb and retain water.In recent years,researchers have conducted a lot of studies on the replacement of traditional petrochemical-based materials with natural biomaterials in synthetic feedstocks in response to the national dual-carbon strategy and the call for the development of new quality productivity.Moreover,with the extensive and in-depth research on the preparation of super absorbent resins,their synthesis mechanisms and synthesis methods have been continuously updated.In addition,significant research progress has been made in the internal structure and property function of high water-absorbent resins,which has enriched the method of introducing characteristic functional groups into the reactive raw materials and formed new composite SARs to match the needs of applications in specific fields.This is mainly based on the unique physicochemical properties of high water-absorbent resins,which are used as a kind of carrier and combined with a variety of materials,thus giving new composites with better performance.This paper reviews the classification of super absorbent resins(SARs),their synthesis methods,and the progress of their applications in recent years.Finally,based on the review and analysis of the synthesis and application of SARs,it expresses the affirmation and outlook of the research on natural-based super absorbent polymers and composite-based super absorbent polymers.The necessity of research and process improvement in SAR synthesis guided by the principles of resource utilisation and ecological sustainability is emphasised.
