Nanowerk  May 6, 2020A team of researchers in the US (Lawrence Livermore National Laboratory, U.S. Army Natick Soldier Research, Development and Engineering Center, MA) demonstrated a smart material that is both breathable and protective by successfully combining a base membrane layer comprising trillions of aligned carbon nanotube pores and a threat-responsive polymer layer grafted onto the membrane surface. The carbon nanotubes could easily transport water molecules through their interiors while also blocking all biological threats, which cannot fit through the tiny pores. To add protection against chemical hazards, a layer of polymer chains is grown on the material surface, which […]
