摘要:

隨著我國現(xiàn)代化工業(yè)進程的加速，以懸浮顆粒物和揮發(fā)性有機物為主的空氣污染物在空氣中的含量迅速上升，空氣質(zhì)量日益惡化，嚴重影響人們的日常工作與生活。氣凝膠因具有比表面積大、孔隙率高、密度低、熱導(dǎo)率低等優(yōu)異性質(zhì)，廣泛用于隔熱隔聲、催化、過濾和生物醫(yī)藥等領(lǐng)域。介紹了氣凝膠常用的制備方法，即溶膠凝膠法，主要包括4個方面：溶膠凝膠過程、老化過程、干燥技術(shù)和碳化過程。綜述了氣凝膠材料在氣溶膠納米顆粒和揮發(fā)性有機物過濾方面的研究進展，同時展望了氣凝膠空氣過濾材料未來的發(fā)展前景。

Abstract:

With the acceleration of domestic modern industrial process, the rapidly rising level of air pollutants such as airborne nanoparticles and volatile organic compounds leads to air quality deteriorating and has serious impact on people�餾 daily work and life. The unique properties of aerogels such as enormous active surface area, high porosity, extremely low density and low thermal conductivity make them attractive materials for several applications ranging from thermal and acoustic insulation, catalysis and filtration to biomedical and pharmaceutical applications. Preparation methods of aerogel materials including sol�瞘el process, aging, drying technology and carbonization were introduced. Progress on the aerogel materials used in the filtration of aerosol nanoparticles and volatile organic compounds was discussed in detail, and an outlook on the future direction of the aerogel materials was made at the same time.
