EMI Shielding Effectiveness of Graphene-Based Composite Coatings

Quick fact

A graphene-based composite coating just a few micrometers thick can block more than 99% of incident electromagnetic interference, matching the performance of much thicker metal foils while being radically lighter and more flexible.

Why this is interesting

Did you know that a coating thinner than a human hair can block signals that would otherwise disrupt your phone? Graphene-based paints are that powerful.
