LLNL’s “Second Skin” Uniform Material to Protect the Warfighter

LLNL flexdemo

High breathability is a critical requirement for protective clothing to prevent heat exhaustion for soldiers in contaminated environments. In work that aims to protect soldiers from biological and chemical threats, scientists from Lawrence Livermore National Laboratory (LLNL) have created a flexible membrane material that is highly breathable, yet protective from biological agents. The team fabricated flexible polymeric membranes with aligned carbon nanotube channels as moisture conductive pores. These pores are 5,000 times smaller than the width of a human hair. This material is the first key component of futuristic smart uniforms that also will respond to and protect from environmental chemical hazards. 

LLNL has a mission of strengthening U.S. security by developing and applying world-class science, technology and engineering that enhances the nation's defense; reduces the global threat from terrorism and weapons of mass destruction; and responds with vision, quality, integrity and technical excellence to scientific issues of national importance.
