摘　　要：二氧化碳(CO2)捕获以及转化是控制大气中二氧化碳含量和有效利用的主要策略。CO2响应型聚合物以含有胺基的烯类单体为主要原料,通过接枝聚合或与其他功能分子复合来改善其对CO2的响应以及捕获性能。其中,天然高分子(如多糖、蛋白质等)具有资源丰富、无毒、可降解和良好的生物相容性等优点,是制备环境友好高分子材料的最佳选择。同时,壳聚糖含有大量的伯胺,在制备基于胺基的具有CO2响应以及捕获性能的智能复合材料中具有潜在优势。本文首先介绍了CO2响应聚合物和壳聚糖的特点,进一步归纳了近年来基于壳聚糖的CO2响应高分子以及捕获材料的最新研究进展,并对这类复合材料的设计及其应用前景进行了展望。It is a main strategy that carbon dioxide(CO2)in the atmosphere is effective utilized,and its concentration is balanced by capture and conversion of CO2.Generally,CO2 responsive polymers are prepared by alkene monomers containing amine groups.Their response and capture properties for CO2 are improved by grafting polymerization or combining with other functional molecules.Natural polymers including polysaccharide and protein are considered as excellent candidates to prepare environmentally friendly polymers because of their rich resources,non-toxicity,biodegradability and good biocompatibility.Additional,chitosan contains a large number of amino groups,so it is employed to prepare CO2 smart materials and exhibits specific advantages.In the current paper,firstly,CO2 responsive polymer and chitosan(CS)are introduced.Secondly,advance in CO2 responsive polymers and capture materials based on chitosan is reviewed.Finally,a prospect for smart materials based on chitosan in the future is provided.
