Figure 2
Nitrogen gas adsorption analyses.
(a) The adsorption–desorption isotherms of the foam, Aerogel-1 and Aerogel-2 samples, with respective VS values of 1.04%, 0.87% and 1.52%. The inset shows an enlarged view of the plot of the foam. (b) Variations in the specific surface areas of the foam and aerogel samples as a function of VS. (c,d) Pore size distributions of the aerogels with different VS.
