Estimating the term…
The present disclosure provides an aerogel composition which is durable and easy to handle, which has favorable performance in aqueous environments, and which also has favorable combustion and self-heating properties. Also provided is a method of preparing an aerogel composition which is durable and easy to handle, which has favorable performance in aqueous environments, and which has favorable combustion and self-heating properties. Further provided is a method of improving the hydrophobicity, the liquid water uptake, the heat of combustion, or the onset of thermal decomposition temperature of an aerogel composition.
A reinforced aerogel composition comprising a silica-based framework and at least one hydrophobic-bound silicon, wherein the reinforced aerogel composition has a ratio of T1-2:T3 of from 0.01 to 0.3 as determined using nuclear magnetic resonance (NMR) spectra.
A reinforced aerogel composition comprising a silica-based framework and at least one hydrophobic-bound silicon, wherein the reinforced aerogel composition has a ratio of Q2-3:Q4 of between 0.1 and 1.5 as determined using nuclear magnetic resonance (NMR) spectra.
