Copper-based graphene (WJCS/F), the graphene is grown on the surface of copper foil, which can provide copper-based single-layer graphene film, double-layer graphene film and few-layer graphene film.

Self-transfer nickel foam graphene (WJSN): Put nickel foam graphene in nickel etching solution to etch nickel, and then move it to the prepared "suspended substrate". After customers get the product, they only need to put it in deionized water. Gentle release yields foamed graphene that can be transferred directly to any substrate. Nickel foam graphene is widely used and can be used as an electrode material for lithium batteries, greatly improving battery capacity, and can also be used in sensors, electrochemical capacitors, etc.

Graphene on nickel foam (WJN): Graphene grows in the structure of nickel foam. Nickel foam graphene is widely used and can be used as an electrode material for lithium batteries, greatly improving battery capacity, and can also be used in sensors, electrochemical capacitors, etc.

Graphene on sapphire substrate (WJSAS/F): Graphene was transferred onto a sapphire substrate. Single-layer graphene film, double-layer graphene film and few-layer graphene film can be provided, and the size of the film can be customized.

PET substrate graphene (WJPS/F): Graphene is transferred to any type of PET. Single-layer graphene film, double-layer graphene film and few-layer graphene film can be provided, and the size of the film can be customized.

Quartz-based graphene (WJQS/F): Graphene is transferred to the surface of any type of quartz flake. Single-layer graphene film, double-layer graphene film and few-layer graphene film can be provided, and the size of the film can be customized.

Suspended self-transfer few-layer graphene (WJSF), on the basis of "bubble-take" graphene, the copper substrate is etched to obtain graphene/protective layer film, and then the graphene/protective layer film is transferred to the prepared On the "suspended substrate", customers only need to gently release the product in deionized water to obtain graphene that can be directly transferred to any substrate.

Suspended self-transfer single-layer graphene (WJSS), on the basis of "bubble-take" graphene, the copper substrate is etched to obtain graphene/protective layer film, and then the graphene/protective layer film is transferred to "suspended". "Substrate", after customers get the product, they only need to gently release the product in deionized water to obtain graphene that can be directly transferred to any substrate.

"Bubble-take" graphene (WJCDS/F) is prepared by spin-coating a layer of protective film on copper-based graphene and then cleaning it. This product is easy to use and can be directly etched into copper etching solution (the etching solution can be ammonium persulfate solution, ferric chloride solution, copper sulfate hydrochloric acid solution, etc.), and then transferred to deionized water to The etching solution can be used after rinsing. Since the cleaning treatment has been done during the preparation of this product, the graphene prepared by this product has a high cleanliness, and customers can "bubble" graphene in the etching solution and easily transfer it to the required place according to their own needs.

Silicon oxide substrate graphene: Graphene is transferred to the surface of any type of silicon wafer or silicon oxide wafer.

Single-sided growth of copper-based graphene (WJCOS/F) is a product that uses a special production process to grow graphene on only one side of the copper foil. It can provide single-layer graphene film, double-layer graphene film and few-layer graphene film , the size of the film can be customized.
