摘　　要：作为环境友好的绿色溶剂,超临界CO2应用越来越广泛,但CO2较低的溶剂化能力很大程度上限制了它的应用范围。设计合成亲CO2聚合物作为表面活性剂、增溶剂,提高超临界CO2的溶剂化能力,是拓展超临界CO2应用的一种重要手段。综述了几类常见的亲CO2聚合物,从聚合物的结构及其与CO2相互作用角度评述了亲CO2聚合物的设计,对亲CO2聚合物在增稠剂、表面活性剂、添加剂和选择性分离膜等方面应用的相关进展进行了介绍,并对亲CO2聚合物设计和应用面临主要挑战和未来发展方向进行了展望。As an environment-friendly solvent,the application of supercritical CO2(scCO2)has been extended more widely in many fields.However,to a large extent,the lower solvating power of CO2limits its industrial application.CO2-philic polymers,as surfactants or solubilizers,can increase the solvating power of CO2and expand the applications of scCO2.This review introduces several kinds of common CO2-philic polymers.Focusing on the structure and the interaction with CO2,the design of CO2-philic polymers and the application advances of these CO2-philic polymers used in thickeners,surfactants,additives and selective separation membranes are reviewed.The main challenges and development trend of the design and application of CO2-philic polymers are also prospected.
