摘要:

高性能CO2吸附劑不僅對控制全球變暖意義重大，而且在航空航天、國防軍工、能源、化工等多個領域有廣泛應用。多孔材料的氨基功能化是開發高性能CO2吸附劑的有效手段，其中氣凝膠具有相互貫通的三維納米多孔網絡結構、大的比表面積和發達的孔隙，是一種理想的氣體吸附材料。探討了氨基功能化氣凝膠材料的CO2吸附機理和吸附性能測試方法，總結了浸漬、表面接枝和原位聚合3種氣凝膠氨基功能化的方法，介紹了相應的3類氨基功能化氣凝膠的制備工藝與CO2吸附性能�？偨Y了3類氨基功能化氣凝膠制備方法及其相應CO2吸附劑的優缺點，展望了氨基功能化氣凝膠CO2吸附劑的應用前景和未來發展方向。

Abstract:

The high-performance CO2 adsorbents are not only significant for the global warming control, but also have wide applications in many other aspects, such as aerospace, energy, environment, etc. Amine functionalization of the porous materials is an effective way to develop high-performance CO2 adsorbents, aerogel of which has interpenetrating nanoporous network, large specific surface area and well-developed porosity, and is an ideal candidate for gas adsorption. In this paper, the CO2 adsorption mechanisms and characterization methods of the amine functionalized aerogels are introduced. Three methods, including impregnation, grafting and in�瞫itu polymerization, to achieve the amine functionalization of the aerogels are summarized. The preparation technologies and CO2 adsorption performances of these three classes of amine functionalized aerogels are reviewed. Finally, the strengths and weaknesses of the preparation methods and the corresponding CO2 adsorbents of these three amine functionalized aerogels are discussed, and the application prospects and the future development directions of the amine functionalized aerogels are forecasted.
