A 3D-printed, ultra-thin, lightweight, high-performance shielding material comprised of two nanotubes has proven effective as a shield against both cosmic electromagnetic waves and radiation. Shielding materials are a necessity in key modern industrial settings-such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices-to protect both equipment and personnel from electromagnetic waves and radiation. But electromagnetic waves and neutron radiation can only be blocked with distinct materials, which are often heavy and inflexible. A flexible film material that blocks 99.999% of electromagnetic waves and reduces neutrons by approximately 72% A research team led by Dr. Joo Yong-ho at the Extreme Environment Shielding Materials Research Center of the Korea Institute of Science and Technology(KIST) have developed a new, lightweight solution to this problem, by combining carbon nanotubes (CNTs), which block electromagnetic waves, with boron nitride nanotubes (BNNTs), which absorb neutrons, to create a shell-structured, composite material capable of simultaneously blocking both types of radiation in a single thin layer.
