[Figure 1] Next-generation ultra-lightweight composite material that simultaneously blocks electromagnetic waves and neutrons

Caption

In space, nuclear, and medical environments, electromagnetic waves and neutron radiation coexist, but existing materials have been limited in their application due to their heavy weight and rigidity. The research team combined carbon nanotubes (CNTs), which block electromagnetic waves, with boron nitride nanotubes (BNNTs), which absorb neutrons, to create a composite material capable of simultaneously blocking both types of radiation in a single thin layer. Furthermore, by combining this with a polymer (PDMS), the team achieved a lightweight and flexible form, demonstrating the potential for this material to evolve into a next-generation shielding material applicable to various structures and devices.
