Grolltex generates high-purity graphene via chemical vapor deposition (CVD) on copper foil substrates of 25 micrometer (μm) thickness. Our expertise in the generation of monolayer graphene on copper is unmatched. We have demonstrated the superior performance of our metal-assisted exfoliation process in transferring monolayer graphene structures from copper foils without consuming the substrate material. This key competency has cemented Grolltex as one of the world’s leading authorities in generating graphene on copper foils as well as on proprietary ‘optimized growth substrates’ for subsequent transfer to other surfaces.
Our copper foils are sourced from the highest quality American suppliers, and all subsequent growth and packaging processes are conducted in a Class 1000 cleanroom environment. We guarantee graphene coverage of at least 95% of the substrate, which is available in sizes up to 8” (200mm) in diameter.
