摘要：

Light support: Regenerated cellulose gel prepared from an aqueous alkali-urea solution serves as scaffold/template for the in-situ preparation of cellulose-silica composite aerogels (see picture) by a sol-gel process from organic silicates, and drying with supercritical CO 2. The resulting composite aerogels have the mechanical strength and flexibility, large surface area, semi-transparency, and low thermal conductivity of the cellulose aerogels.
