Ultrathin, stretchable nanotube composites offer innovative EMI and neutron shielding, ideal for electronics in extreme environments like aerospace and defense. Ultrathin, stretchable, and 3D-printable nanotube composites can shield electronics from both electromagnetic interference (EMI) and neutron radiation in extreme environments. Study: Ultrathin, Stretchable, and 3D-Printable Complementary Nanotubes–Po... [6264 chars]
