Creating products based in single layer, CVD generated graphene of the highest quality.

Grolltex, short for ‘graphene-rolling-technologies’, is an advanced materials and equipment company located in the Scripps Ranch area of San Diego, California.

Through patented transfer and processing methods, we are able to produce single layer graphene at a cost structure not previously known.

Our methodologies enable the design of world class graphene products, as well as the equipment used for graphene transfer that reuses and optimizes the previously ‘sacrificial’ copper substrate. This optimization and reuse of the copper substrate enables cost, throughput and quality advantages that competing graphene production technologies cannot match. Additionally, our processes enable new graphene product designs and directions in the areas of sensing, OLED’s, barrier materials, bio-sensors and many more. For example, we have created what we believe is ‘the smallest, most sensitive strain sensor in the world’. At one atom thick, it’s pretty small and so far, we haven’t found any competing sensitivity results that are better.
