This technology also has potential as a transparent barrier for encapsulation of atmosphere sensitive technologies, such as organic LEDs for solid state lighting. It also has potential application as a high performance filter material when patterned with precisely size holes, as a chemical sensor, as low-dimensional transistor, and as a flexible transparent conductor. Development of the production tools and methods are essential to all these applications. This program will develop ultra-lightweight, durable, reliable, and flexible gas-impermeable barriers for the walls of inflatable structures for space applications. This technology will prove highly advantageous for habitat design and construction. In addition to structures in space and on the moon or other celestial bodies, this technology to develop ultra-lightweight impermeable fabrics has potential application for space suits, solar sails, and impact attenuation airbags for vehicle landings.
