Title: Highly filled carbon nanofiber reinforced polysiloxanes

Abstract

Provided herein are polysiloxane-based composite materials comprising a high weight percentage of elemental components (e.g., elemental boron, elemental copper, elemental bismuth, elemental lead) and low levels of carbon nanofibers. The elemental components may be present in the composite materials at levels greater than 25% by weight. Also provided herein are methods of forming the composite materials that have desirable flexibility and shielding properties. The invention provides a versatile composite material that is compliant and moldable, while still comprising high levels of the elemental shielding components. The materials are particularly useful for applications in which radiation shielding or neutron capture are desired.
