The invention discloses an aerogel preparation method based on hydrothermal solvent replacement. The method comprises the step of soaking inorganic oxide hydrogel with low salt content in acid liquor. And then replacing water in the hydrogel with an organic solvent under a hydrothermal condition. And finally, drying to obtain the aerogel.
本发明公开了一种基于水热溶剂置换的气凝胶制备方法。此方法包括将低含盐量的无机氧化物水凝胶浸泡在酸液中。然后在水热条件下将水凝胶中的水用有机溶剂置换。最后通过干燥得到气凝胶的方法。
