For further demonstrating the flexibility and absorbance rate of the compressed cellulose aerogels (in Table 1b),
we used a cellulose aerogel absorbing 7.4 times of its dry weight of water for 20 min in the first test.
Normally, absorbed water can only be removed from super absorbent polymers by drying.
In contrast, water absorbed by the cellulose aerogel is removed easily by simply squeezing it (Fig. 3d).
