Abstract: 
The average density of the obtained dry cellulose aerogels is only about 8 mg cm⁻³ which is comparable to the most light-weight silica aerogels and distinctly lower than all values published so far for cellulosic aerogels. SEM, ESEM, nitrogen adsorption experiments at 77K, and thermoporosimetry reveal an open-porous network structure that consists of a comparetively high percentage of large mesopores and smaller macropores.
