Could Aerogel Become a Facility Staple?

 
Aerogels may become an option for energy-efficient building insulation.

A major improvement in the world's lightest solid material and best solid insulating material, described here today, may have huge impact on insulated clothing, refrigerators with thinner walls that hold more food, building insulation, and other products.

The report, on development of flexible "aerogel" ― stuff so light it has been called "solid smoke" ― was part of the 244th National Meeting & Exposition of the American Chemical Society.

Mary Ann B. Meador, Ph.D., explained that traditional aerogels (watch a video from the Lawrence Livermore National Laboratory), developed decades ago and made from silica, found in beach sand, are brittle, and break and crumble easily. Scientists have improved the strength of aerogels over the years, and Meador described one of these muscled-up materials developed with colleagues at the NASA Glenn Research Center in Cleveland, Ohio.

"The new aerogels are up to 500 times stronger than their silica counterparts," Meador said. "A thick piece actually can support the weight of a car. And they can be produced in a thin form, a film so flexible that a wide variety of commercial and industrial uses are possible."

Flexible aerogels, for instance, could be used in a new genre of super-insulating clothing that keeps people warm in the cold with less bulk than traditional "thermal" garments. Tents and sleeping bags would have the same advantages. Home refrigerator and freezer walls insulated with other forms of the material would shrink in thickness, increasing storage capacity. Meador said that the aerogel is 5-10 times more efficient than existing insulation, with a quarter-inch-thick sheet providing as much insulation as 3 inches of fiberglass. There could be multiple applications in thin-but-high-efficiency insulation for buildings, pipes, water heater tanks and other facility favorites.

Scientists produced the stronger new aerogels in two ways. One involved making changes in the innermost architecture of traditional silica aerogels. They used a polymer, a plastic-like material, to reinforce the networks of silica that extend throughout an aerogel's structure. Another involved making aerogels from polyimide, an incredibly strong and heat-resistant polymer, or plastic-like material, and then inserting brace-like cross-links to add further strength to the structure.
