| 中文摘要: |
| 气凝胶具有低密度、低热导率、高比表面积及高孔隙率等优异性能，在隔热、传感、催化、吸附、储能等领域显示出良好的应用前景。但气凝胶的多孔网络结构也造成了其强度低和韧性差问题，严重制约了气凝胶的实际应用，有机-无机复合是一种增强气凝胶力学性能的有效方法。近年来，采用有机-无机复合方法制备气凝胶还可以赋予气凝胶阻燃等其他新颖的性能。本文论述了有机-无机复合气凝胶的最新研究进展，分析其原理、合成方法及相关性能，指出了有机无机复合气凝胶的优势和存在问题并展望了未来发展方向。 |
| 英文摘要: |
| Aerogels have excellent properties such as low density, low thermal conductivity, high specific surface area and high porosity,which have a good application prospect in the fields of heat insulation, sensing, catalysis, adsorption and energy storage. However, the porous network structure of aerogels also causes low strength and poor toughness, which seriously restricts their practical application. Organic-inorganic composite process is an effective method to enhance the mechanical properties of aerogels. It has been found in recent years that the preparation of aerogels by organic-inorganic composite method can also impart other novel properties to aerogels, such as flame retardancy. In this paper the new research process in organic-inorganic composite aerogels was summerized, and its analyzes its principle, synthetic methods and related properties were analyzed. Finally, the advantages and problems and the future development direction were diseassed organic-inorganic composite. |
