Abstract
Aerogels are open-pore, ultra-low density solids with very high surface areas, low thermal conductivities, high acoustic impedance, and low dielectric constants. Because of these properties, aerogels are attractive multifunctional materials for applications in aerospace, automotive, chemical, and construction industries. However, aerogels are often rigid and fragile. That is addressed herein with two different types of polyurethane aerogels, where flexibility is imparted by varying the chemical structure and concentration of the monomers.
These flexible aerogels may find use in highly insulating clothing for divers, astronauts, and mountain climbers. Their high surface area may find applications as catalyst supports, in microfluidic devices used in biotechnology, and in fuel cells. Importantly, the impressive strength-to-weight ratio of higher-density polyurethane aerogels renders them attractive as energy absorbers for defense applications.
