Layered polymer nanomaterial wraps around penetrating particles
You don’t have to be a caped superhero to stop a speeding bullet. Scientists have created a material that demonstrates how common plastics can bring projectiles traveling faster than a kilometer per second to a screeching halt. Similar materials might be used to make supertough lightweight body armor, or coatings to protect jet engine components or spacecraft from flying debris.
“This may provide a way to make new materials that are more durable,” says Catherine Brinson, a specialist in advanced materials at Northwestern University in Evanston, Ill., who was not involved with the work. “There may be app
