A groundbreaking new discovery could result in the creation of an incredible strong but light armor that could stop bullets and could be using in the military, or by police. The paper, published by  scientists from City University of New York’s Advanced Science Research Center in the journal Nature Nanotechnology, detailed researchers’ attempts to merge two graphene layers into the new material.

The material is incredible thin, as thin as aluminum foil, but when pressure is applied it becomes rigid, but still very light. The new material could be used to create lightweight protective vests for soldiers and officers, as it is so strong that it could stop many different deadly objects.

Scientists used computer simulations first, determining how they might create this new material, combining two graphene layers together. Then, they used an atomic force microscope to pressurize the layers and create the rigid material.
