TLDR
The design of such a filigrane network requires the very careful control of chemical parameters and the reward is an assortment of different property profiles owing to the richness of possible variations.Abstract:
Air, air, air… and some solid skeleton; this is the basis for an interesting class of materials-the aerogels (shown schematically on the right). Can one therefore speak of "simple" chemistry? The design of such a filigrane network requires the very careful control of chemical parameters. The reward is an assortment of different property profiles owing to the richness of possible variations.read more

Hydrogen bonding directed assembly of simonkolleite aerogel by a sol–gel approach
TL;DR: In this article, a metal-based inorganic aerogel and the sol-gel technique can be developed for industrial applications, which exhibits a pore size distribution around 17-19nm, a compressive modulus up to 2-4MPa comparable to carbon nanotube arrays, and strong photoluminescence in a blue band around 416-437nm.

Preparation of poly(aryl ether ketone ketone)–silica composite aerogel for thermal insulation application
TL;DR: In this article, a cross-linked poly(aryl ether ketone ketone) (PEKK) with trimethoxysilane pendant groups was formed through the hydrolysis and condensation reactions.

Towards Porous Silicon Oxycarbide Materials: Effects of Solvents on Microstructural Features of Poly(methylhydrosiloxane)/Divynilbenzene Aerogels.
TL;DR: It is postulate that solubility and swelling of the cross-linked polymer in various solvents are major factors governing pore formation of these PMHS/DVB polymer aerogels.
