Aerogel is well-known as a kind of high-performance thermal insulation material with nano-porous structure[1].Silica aerogel is the most widely used aerogel.Monolithic transparent silica aerogel combines the advantages of light-transparency and thermal insulation, but it is difficult to be applied in industry, the reasons are: 1) it is hard to get due to its brittleness and 2) the large-scale preparation is difficult to be realized because of its low efficiency and high cost[2].Cellulose aerogel with good transparency and flexibility has been reported[31, but the structure of this kind of aerogel is not stable, it can easily absorb aqueous vapor to induce shrinkage.
