摘要:

氣凝膠材料是一種具有低密度、高孔隙率、高比表面積、低折射率、低介電常數(shù)等特性的納米多孔材料，在航空航天、石油化工、環(huán)境處理、建筑保溫、能量?jī)?chǔ)存與轉(zhuǎn)化等領(lǐng)域具有廣泛的應(yīng)用價(jià)值。重點(diǎn)介紹了國(guó)內(nèi)外二氧化硅基氣凝膠和有機(jī)氣凝膠的組成、結(jié)構(gòu)、制備和性能方面所取得的突破性進(jìn)展，其中二氧化硅基氣凝膠主要從耐高溫氣凝膠、疏水氣凝膠和低成本氣凝膠3方面進(jìn)行論述，有機(jī)氣凝膠主要包括聚合物基有機(jī)氣凝膠和生物質(zhì)基有機(jī)氣凝膠。綜述了氣凝膠材料在絕熱和吸附領(lǐng)域的最新研究和應(yīng)用，最后對(duì)氣凝膠材料未來(lái)的發(fā)展方向進(jìn)行了展望。

Abstract:

Aerogels have many unique properties, such as low bulk density, high porosity, high specific surface area, low refractive index and low dielectric constant, etc. Therefore, aerogels have many promising applications in many fields such as aerospace, industry, environmental protection, building energy saving, energy storage and conversion, etc. In this paper, the representative studies and research progress of aerogel fabrication, development and applications with respect to silica�瞓ased aerogels and organic aerogels are provided. Silica�瞓ased aerogels include high�瞭emperature aerogels, hydrophobic aerogels and cost�瞖ffective aerogels, while organic aerogels can be classified as polymer�瞓ased organic aerogel and biomass�瞓ased organic aerogels. The research advances on aerogel�瞓ased thermal insulations and adsorbents are summarized. The prospects of aerogel application development are also reviewed in this paper.
