Graphene Rolling Technologies & the Global Graphene Expo

In this interview, AZoNano spoke with Jeff Draa, the CEO and Co-Founder of Grolltex, about their Graphene rolling technologies and the Global Graphene Expo.

Please tell us a bit about Grolltex and your role.

Grolltex, short for ‘graphene-rolling-technologies’, is the largest capacity commercial CVD facility in North America.  We specialize in single layer graphene and hBN, with a particular expertise in the ‘transfer’ of graphene from the copper growth substrate to target surfaces of interest, in a manufacturable and repeatable way.

My role is CEO and I am also a co-founder.

What Graphene products do you offer?

We currently sell large-area single-layer graphene and hBN in three formats; on copper, on silicon wafers – 4”, 6” and 8” – and on YOUR substrate of interest.

Can you tell us about your ‘Graphene Accelerator’ and how that works?

We are currently characterizing heterostructures of graphene and hBN, meaning we can layer these 2D materials together in any combination. What we’re finding is that graphene layered on top of hBN exhibits a dramatic increase in carrier mobility, meaning the graphene is capable of being much more conductive sitting on top of hBN than it is on something else or by itself. This could be a very big deal to electronic device designers.

What makes your materials unique in the marketplace?

Well, we certainly aren’t the only ones doing CVD graphene, however we think we have two advantages over others. The first is quality, as we have set a new bar for selling CVD graphene. Watching our competitors react to our product offerings, we know we’re doing something right.

Secondly, we seem to be the only ones trying to tackle the ‘transfer’ problem, as we don’t see any other answers out there. We are very focused on the ‘industrialization’ of graphene and all our advancements are related to this.  

How do you think Graphene will develop and improve our technology and day-to-day lives?

I believe that some of the structural graphene offerings will impact us first, providing stronger products that last longer.

What can we expect from your presentation at the Global Graphene Expo this year?

We will be underlining the theme that CVD graphene is ready for prime time, talking about our commercialization efforts as well as some new customer activities that are helping us go industrial.

Why do you think that conferences like the Global Graphene Expo are important?

Conferences like this, especially events that focus on industrialization such as this one, are really helping to take the perception of graphene out of the lab and onto the factory floor. When we can talk in tangible terms with attendees about how we can improve the performance of their existing devices, while quoting prices and throughputs that are truly usable for large manufacturers, then we can really make a difference.
