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

Superflexible Multifunctional Polyvinylpolydimethylsiloxane-Based Aerogels as Efficient Absorbents, Thermal Superinsulators, and Strain Sensors.
TL;DR: Unprecedented superflexible aerogels based on polyvinyl polydimethylsiloxane networks, PVPDMS/polyvinylpolymethyl siloxane copolymer networks, and PVPD MS/PVPMS/graphene nanocomposites are reported by a facile radical polymerization/hydrolytic polycondensation strategy and ambient pressure drying or freeze drying.

TL;DR: The assembly process, based on a physical concept, is highly versatile: cryogelation is applicable for noble metal, metal oxide, and semiconductor NPs, and no impact of the surface chemistry or NP shape on the resulting morphology is observed.
