摘要：二氧化碳(CO_(2))刺激响应型聚合物是指在向聚合物体系中引入或排除CO_(2)后,聚合物物理结构与化学性质等发生可逆变化的“智能”大分子,在各科学领域具有广阔的应用前景.本文从CO_(2)响应基团出发,分类介绍不同种类CO_(2)响应基团的作用机理,随后依次综述了CO_(2)响应型聚合物的合成、表征、智能体系及其应用领域.最后讨论与总结该类聚合物材料现存的挑战,并对其未来应用前景与发展方向进行了展望.
CO_(2) is a benign,inexpensive,abundant,and non-toxic trigger for stimuli-responsive materials,and has received increasing attention in recent years.CO_(2) stimuli-responsive polymers,as an attractive type of“smart”macromolecules,undergo a reversible transition in the physical and chemical properties of polymers when CO_(2) is introduced or excluded from the polymer system,exhibiting broad application prospects in various scientific fields.Herein,this review summarizes the recent development of CO_(2)-responsive polymers and introduces the working mechanisms of different types of CO_(2)-responsive groups from chemical structures,including amidines,tertiary amines,guanidines,imidazoles,and frustrated Lewis pair(FLP).Methods for the synthesis of CO_(2)-responsive polymers are introduced,including free radical polymerization(FRP),reversible addition-fragmentation chain-transfer(RAFT),atom transfer radical polymerization(ATRP),nitroxide-mediated polymerization(NMP),and postpolymerization modification.Subsequently,the techniques for the characterization of CO_(2)-responsive polymers are summarized,including structural characterization using 1H-NMR and FTIR,and property characterization using measurements of pH,conductivity,Zeta potential,and transmittance.Assemblies,latexes,gels,composites,and membranes with CO_(2) responsiveness are introduced separately from the perspective of smart response systems,and the current status of these developments is summarized.Among these,research on the second generation of CO_(2)-responsive systems is highlighted,which are based on the“dynamic gas bridge”formed between boron/phosphorus frustrated Lewis acid-base pairs and carbon dioxide gas molecules.Meanwhile,a stepwise summary of CO_(2)-responsive polymers for CO_(2) capture,smart catalysts,protein adsorption,controllable separation,fluorescence sensing,and drug delivery is presented.Eventually,the current challenges toward the development of CO_(2)-responsive polymers are discussed and summarized,accompanied by an outlook of the future application prospects and development directions.Large-scale production of CO_(2)-responsive polymers remains a significant challenge,while further investigation of the response mechanism to improve the sensitivity and cyclic stability of the response process will provide the basis for the development of CO_(2)-responsive materials that have a broader range of applications.
