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

Ultralight conducting polymer/carbon nanotube composite aerogels
TL;DR: By embedding carbon nanotubes into poly(3,4-ethylenedioxythiophene) and poly(styrenesulfonate) supermolecular hydrogels in the presence of a very small amount of polyvinyl alcohol (PVA), the fabrication of ultralight conducting polymer/carbon nanotube composite aerogels with the apparent density of 0.04-0.07lg/cm 3 made by supercritical CO 2 drying of as-made composite hydrogel precursors was presented in this paper.

Ambient-pressure drying synthesis of large resorcinol–formaldehyde-reinforced silica aerogels with enhanced mechanical strength and superhydrophobicity
TL;DR: In this paper, a facile sol-gel route was developed to fabricate a large (500 cm3) polymer-silica aerogel monolith that was stable under atmospheric conditions and suitable for machining.

Enhancements of thermal insulation and mechanical property of silica aerogel monoliths by mixing graphene oxide
TL;DR: In this paper, the thermal insulation property of composite aerogels was improved in contrast with that of pure aerogel by adding the graphene oxide (GO) as a nanofillers into the SiO2 matrix.
