Researchers construct molecular nanofibers that are stronger than steel

Self-assembly of Kevlar-inspired molecules leads to structures with robust properties, offering new materials for solid-state applications.

Researchers have designed small molecules that spontaneously form nanoribbons when water is added. These molecules include a Kevlar-inspired “aramid” domain in their design, which fixes each molecule in place and leads to nanoribbons that are stronger than steel. This image depicts three Kevlar-inspired “aramid amphiphile” nanoribbons.
