The graphene film is grown on the surface of the copper foil, and the number of layers grown is a single layer or a few layers (less than 10 layers). The film has high integrity, high single-layer coverage, good electrical conductivity, and a mobility of ~6000 cm2/vs.

The "bubble-take" graphene is obtained by spin-coating graphene on a copper substrate with an organic polymer protective film (the customer has omitted this step), and then undergoing ultra-clean treatment on the back. This kind of graphene is very convenient. It can be directly put into the etching solution to etch away the copper, and then transferred to deionized water to rinse off the etching solution for use. Since it has been cleaned, the graphene obtained by this method is very clean. Customers can "bub" the copper substrate in the etching solution and "take out" the graphene, which can be easily transferred to Where needed.

This product should be sealed and stored in a dry environment, and the temperature is below 35 ℃. Contact with volatile substances and pollution sources is strictly prohibited. Keep away from fire.

Remarks: A-level single-layer coverage is greater than 97%, B-level single-layer coverage is greater than 85%, and few layers of graphene are less than 10 layers thick. Customized services are available
