二氧化碳在聚氨酯中的资源化应用

Utilization of carbon dioxide in polyurethane

  • 摘要: 随着现代社会的快速发展,人们对能源的需求与日俱增,目前,发展中国家仍以化石燃料为主要能源投入,其燃烧产生的二氧化碳排放带来的温室效应和环境问题已引起举世关注。因此,通过对二氧化碳进行捕集、封存与转化利用,实现碳减排和碳中和目标成为目前研究的热点。其中,二氧化碳基高分子材料的制备在实现二氧化碳资源化利用的同时,也为聚合物的绿色生产提供了新思路。基于此,本文综述了二氧化碳在聚氨酯中的资源化利用现状,着重对其在材料中的物理、化学应用进行了阐述,并详细介绍了在转化利用过程中的制备技术和方法。

     

    Abstract: With the rapid development of modern society, the demand for energy is increasing. Currently, fossil fuel is still the dominant energy in developing countries. Moreover, the greenhouse effect and environmental problems result from excessive emission of carbon dioxide by the combustion of fossil resources have arouse worldwide concern. Therefore, utilization of carbon dioxide has attracted much attention. Among the paths, the preparation of polymers from carbon dioxide could not only realize the carbon fixation, but also provide a new approach for the green production of polymer. This review aims to summarize the progress on the synthesis of polyurethane from carbon dioxide, which mainly focuses on its physical and chemical applications in materials and the preparation technologies.
