Ultra-Conductive Graphene Sheets
This highly conductive graphene material is often used in electronic devices, such as cell phones, laptop computers, digital cameras, and LEDs. It can be folded without tearing or damaging the sheet and can be cut into smaller pieces with scissors. Thickness, width, and length tolerances are not rated.

Ultra-Conductive Graphene on Copper Foil
Grown by chemical vapor deposition (CVD) on copper foil, this highly conductive graphene material can be transferred using chemical methods such as polymer-supported metal etching, and mechanical methods such as thermal release tape and direct transfer. This graphene foil is 200 times stronger than steel by weight and is also flexible. It comes taped to the corners of a plastic container in a double vacuum-sealed bag to maintain shelf life. Do not remove the packaging until ready to use. Gently peel the tape or cut the corners of the foil to release. Use rolling blades or precision knives to cut the foil.
