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.
