摘要
气凝胶材料具有低密度、低导热系数和高孔隙率等特点,在建筑、能源等领域具有广泛的应用前景.然而,传统的气凝胶制备方法通常需要复杂的工艺和昂贵的原料,严重限制了气凝胶材料的规模化生产和商业化应用.因此,研究人员开始关注低成本制备气凝胶材料的方法.本文综述了近年来在低成本制备二氧化硅气凝胶材料方面的研究进展,包括硅源的选择、干燥方法等.希望通过本文的介绍,能够为气凝胶材料的低成本制备提供一定的参考和指导.
Abstract
Aerogel materials,renowned for their low density,low thermal conductivity,and high porosity,have found extensive applications in construction,energy,and other fields.However,traditional aerogel preparation methods often involve complex processes and costly raw materials,significantly impeding their large-scale production and commercial utilization.Therefore,researchers have turned their attention to developing cost-effective strategies for aerogel production.This paper delves into recent advancements in the low-cost synthesis of silica aerogels,encompassing the selection of silicon sources and drying techniques.It is expected that this review will offer valuable insights and direction for future endeavors in the economical fabrication of aerogel materials.
