Advanced thermal insulation and absorption properties of recycled cellulose aerogels

- For the first time, paper waste can be converted into a green cellulose aerogel.
- The material has high water/oil absorption capacities of 18-20 times of its weight.
- Up to 99.8% of the liquid is recovered simply by squeezing the aerogel.
- The material shows low thermal conductivities of 0.029-0.032 Wm−1K−1.
- The aerogel shows good flexibility and mechanical property.
