2011年7月28日 · Polymer-enhanced aerogels and polymer-based aerogels have numerous potential applications, both in space, on distant planets and on our own Earth. They are light, durable and extremely effective at insulating and preventing heat transfer.

Aerogel structure results from a sol-gel polymerization, which is when monomers (simple molecules) react with other monomers to form a sol or a substance that consists of bonded, cross-linked macromolecules with deposits of liquid solution among them.

What are Aerogels? Aerogels are a class of porous solids which exhibit many extreme properties which originate from a nanoporous skeletal architecture • Highly porous solids made by drying a wet gel without shrinking • Pore sizes extremely small (typically 10- …

Polyamide aerogels open up a whole new world of applications due to their unique properties: translucent like silica aerogels; thermoplastic; ultra-low density; superior mechanical properties; low-temperature operating range; and highly flexible (as compared to …

Aerogels make excellent electrical, thermal, and acoustic insulators. However, most inorganic silica aerogels are fragile and shed dust. The NASA Glenn team is the first to synthesize three-dimensional polymer aerogel networks of polyimides cross-linked with …

Recently, aerogels based on natural or synthetic polymers, called polymer or organic aerogels, have been widely explored due to their porous structures and unique properties, such as high specific surface area, low density, low thermal conductivity and dielectric constant.

• Build out of ultra-lightweight, low dielectric polymer aerogels – Up to 80% weight savings by using unconventional materials • Reduced drag through use of conformal designs

In this study, a comprehensive review on polymer based hybrid aerogels is presented, including polymer–polymer, polymer–carbon material, and polymer–inorganic hybrid aerogels, which will be introduced and discussed in view of their chemical structures and hybrid structures.

With unmatched shape control, compositional tailoring, and monolith manufacturing capabilities, Aerogel Technologies makes silica, carbon, polymer, and metal aerogels accessible and affordable for a wide range of scientific and engineering applications.

2012年9月27日 · Meador and her team have developed a particularly encouraging form of polymer aerogel, which is strong, flexible, and robust against folding, creasing, crushing, and being stepped upon.
