TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Thin films, elastomeric materials, high temperature fabrics and adhesives that are capable of withstanding thermal extremes (-130oC to 500oC) are highly desirable for use in inflatable decelerator applications. One solution is to substantially increase the thermal conductivity of the adhesive layer underneath the thin film layer so that heat generated during entry of the decelerator into the atmosphere can be quickly and effectively dissipated, thus avoiding the negative effect of high temperature. We propose an approach wherein a low volume fraction (<5%) of inorganic nanoparticle fillers will lead to substantial increase in thermal conductivity in the direction perpendicular to the thin film. The innovation is in the development and processing of a unique morphology of the nanocomposite adhesive material. In Phase I, we will demonstrate the feasibility of the concept by fabricating elastomeric adhesives containing nanoscale additives, and testing the thermal conductivity perpendicular to the thin film direction. The Phase I program is a collaboration with a leading manufacturer of inflatable structures for space applications. The focus of the Phase II program will be in implementing the technology in a prototype component, which will be tested and qualified, and made available to NASA. The proposed work builds upon NEI's prior experience with nanoparticle dispersed material systems.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Thermally conductive adhesives provide thermal management through dissipating heat away effectively from the surface of earth-orbiting spacecraft, the human lunar habitat, landers, rovers, and more. The inflatable decelerator is just one example.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Heat conducting polymers are used as interface bonding materials in 'ever-smaller and more power-hungry electronics'. They are also used as tubing for heat exchangers in appliances, lighting, telecommunication devices, business machines, and industrial equipment used in corrosive environments. Lighting applications also include reflectors, laser-diode encapsulation, and fluorescent ballasts. Thermally conductive compounds are also used to encapsulate small motors and motor bobbins. A diesel fuel pump uses a thermally conductive plastic to help keep fuel flowing in sub-freezing temperatures.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
