摘要
高吸水树脂具有优异的吸水性能和保水性能,但高吸水树脂吸水膨胀难以降解对生态环境会造成污染,导致其应用范围受到一定限制.以纤维素为接枝骨架合成的高吸水树脂具有优异的降解性,文章介绍了60Co-γ射线引发、超声波引发、溶液聚合、乳液悬浮聚合等纤维素基高吸水性树脂合成方法的研究进展及优缺点,详细阐述了纤维素基衍生物羧甲基纤维素和羟丙甲基纤维素高吸水树脂近年来的研究进展,并对纤维素基高吸水性树脂在农业、卫生用品、医药和重金属吸附等方面的应用前景进行分析与展望.
Abstract
Super absorbent resins have excellent water absorption and water retention properties,but they are difficult to be degraded by water absorption and swelling,which may cause pollution to the ecological environment,leading to a certain limitation of their application.The super absorbent resin synthesized with cellulose as graft skeleton has excellent degradability.This paper introduces the research progress,advantages,and disadvantages of the synthesis methods of cellulose-based super absorbent resin such as 60Co-γ ray initiation,ultrasonic initiation,solution polymerization,and emulsion suspension polymerization.The research progress of cellulose-based derivatives carboxymethyl cellulose and hydroxypropyl methyl cellulose super absorbent resin in recent years is described in detail,and the application prospects of cellulose-based super absorbent resin in agriculture,sanitary products,medicine,and heavy metal adsorption are analyzed and prospected.
