Design and Synthesis of Novel Hydrogen-Rich Polyimides for Radiation Shielding
Hill, David J.

Abstract
In space, there are several types of radiation, including solar radiation and galactic cosmic radiation (GCR), that can be harmful to both living beings and machines. The current radiation shielding available on spacecraft is insufficient to protect astronauts and sensitive equipment for long-duration space flight or extraterrestrial habitation, and terrestrial shielding techniques are too heavy to be practical for spacecraft. The use of polymers, specifically hydrogen-rich, aromatic polyimides, as radiation shielding provides a method of slowing radiation in space and preventing the damaging cascade of radiation that results from its collision with spacecraft. This research focuses on the development of novel aromatic-ether dianhydrides for use in polymerization with similarly structured diamines to produce hydrogen-rich polyimides for use as radiation shielding.
