Our 25 micron-thick copper foil is sourced from a reliable, quality-assured supplier in the United States. As part of our commitment to delivering the highest quality graphene at affordable prices, our in house substrate processing results in copper grain sizes that are tens of square centimeters in area.
3” x 3” graphene/copper foil pieces are secured to their underlying plastic containers with four small Kapton tape pieces, one in each corner. Gently peel the tape or cut off the corners of the foil to release the foil from the plastic container.

“*The indicated product metrics are generic to our transfer process. For all graphene-on-copper products, the displayed range represents electronic data that we have obtained using our in-house transfer capabilities to transfer graphene to SiO2. Your own mobility and sheet resistance numbers will depend entirely on the transfer methods that you use, and the resultant quality of your transfers.
Data files for mobility and Raman measurements are available upon request. Please send an email including your name, institution, and product serial number to firstname.lastname@example.org and indicate which file(s) you would like.
