Nanolayered, Self-healing Radiation Shielding Foils


EMSL Project ID
44890

Abstract

Recent discovery and research indicate that materials can be hardened against radiation damage by building nanolayered structures with an optimized layer thickness to increase point defect recombination relative to a non-layered structure and that can self-heal. This project will develop the fundamental physics of radiation damage for nanolayered shielding materials based on our understanding of the layered atomistic structures, including strain gradients and interface physics, in a radiation field. Experiments will be carried out to understand the radiation effects on multi-layered metal films generated at EMSL. Attempts will be made to scale the results to large-area metallic foils made by roll-to-roll sputtering.
