Utilization of carbon dioxide in polyurethane

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.
