An Analysis of The List of Graphene Companies by Sector, Country and Public vs. Private

I recently read an article from which extrapolated data on global graphene manufacturing by country and manufacturing type. The data showed that the majority of graphene companies were based out of the United States with China in second.

Additionally their research showed that of the 76 graphene companies in their sample, 72% employed top down graphene production. Top down production is manufacturing graphene by means of graphite exfoliation. The leading alternative is the CVD or chemical vapor method which entails growing graphene on a layer of copper or silicon dioxide substrate.  Their research methodology is not completely known as sources of data were not provided.

This got me wondering, what does’s List of Graphene Companies show? The list currently contains 152 companies. Here are the results:
