Hydrogen-rich Interpenetrating Polymer Networks for Radiation-Shield Structures

The proposed multifunctional high-performance polymers will find application in NASA missions in protecting astronauts and sensitive optical, electronic, thermal and acoustic components from space hazards, including radiation, dust and thermal transients, while, at the same time, providing lightweight structures for planetary rovers and habitats. It is expected that these interpenetrating polymer network systems will provide a high-performance-to-weight radiation shield that can be used within human habitats, spacecraft and protective apparel. Other missions supported by NASA could also make use of the multifunctional materials for the International Space Station or in other orbiting vehicles involving long-duration small dose exposure.

Lightweight multifunctional radiation shielding will find application in the commercial sector in reducing collateral damage from heavy charged particles emerging as a therapeutic approach in nuclear medicine. The shielding will lead to decreased fatigue among medical personnel required to wear heavy protective garments during radiological procedures. Workers in industrial facilities using radiation for materials processing and in nuclear power facilities will also benefit from more-comfortable garments having reduced weight and thermal stress. The Departments of Defense and of Homeland Security will find applications that include protection of soldiers, first responders and emergency medical personnel against high energy gamma radiation and neutrons resulting from so-called dirty bombs as well as from hazards brought about through accidental release of radiological materials.
