摘要
综述了SiO2气凝胶的原料、凝胶工艺、干燥工艺、性能与应用的基本规律和最新进展,展望了SiO2气凝胶未来的研究方向。在SiO2气凝胶优异性能被广泛认同的前提下,工艺研究的重心集中在克服低成本化和强度、吸湿性等,应用研究主要集中在热学、吸附与催化等领域。
The principles and the latest developments of silica aerogels are reviewed, including raw materials, gelation technologies, drying technologies, performances and applications. Also the current and the future research trends are evaluated briefly. While the outstanding performances of silica aerogels have been recognized wildly, the preparation technologies are centered on lower cost processes and improvements in some main defects of silica aerogels. At the same time, study on thermal insulation, absorption and catalysis is the mainstream in the application fields.
