Graphene is probably the most hyped material of the past decade, but so far commercial applications have been limited. Graphene is mostly used as an additive inside composites and plastics to enhance their thermal or structural properties. In the most recent high profile case, Huawei announced the integration of a passive graphene cooling film to improve heat management inside one of their smartphones. While this is a useful use of graphene, it is a far cry from the disruptive electronics that were promised when the material was first isolated.
It is worth considering that both investments and patent filings in graphene peaked in 2015. Nearly four years later, we can expect to see some of these to start paying off with some product launches.
