Energy Absorbing Materials
Environmental Concerns
The production and use of silica aerogels is environmentally
benign. No significantly hazardous wastes are produced during their
production. The disposal of silica aerogels is perfectly natural.
In the environment, they quickly crush into a fine powder that is
essentially identical to one of
the most common substances on Earth, namely, sand. Additionally,
silica aerogels are completely non-toxic and non-flammable. If they
eventually find their way into widespread use as protective
materials, they could eliminate a very large amount of unwanted
plastic materials.
Potential Uses
The attractive energy absorbing properties of silica aerogels may
lead to their use in various applications. These may include
personal protection in motor vehicles, protection of sensitive
equipment such as aircraft flight data recorders, and protection of
electronic equipment such as laptop computer hard drives.
