Two-dimensional polymer helps create a new lightweight material that is stronger than steel

"material's elastic modulus—a measure of how much force it takes to deform a material—is between four and six times greater than that of bulletproof glass... yield strength, or how much force it takes to break the material, is twice that of steel... made from monomers that lock together like LEGOs, and molecules cannot get between them. This could allow us to create ultrathin coatings that can completely prevent water or gases from getting through"
