Products
Monolayer and few-layer CVD graphene films (roll format)
Large-area monolayer and few-layer graphene films produced by atmospheric-pressure roll-to-roll CVD on metal foil; available as graphene-on-catalyst, polymer-coated, or transferred to customer substrates.
3D graphene foam (freestanding porous foam)
Freestanding porous 3D graphene foam produced via template-assisted CVD on metal foam followed by template etch; offered as scaffold material or integrated into composites on request.
Pyrolytic carbon films on substrates
Conformal pyrolytic carbon thin films deposited by CVD-based processes directly onto substrates such as quartz, alumina and silicon; reported film thickness range from ~50 nm to ~2.5 µm with low resistivity and thermal/chemical stability.
Disposable carbon film electrode on ceramic substrate
Disposable electrode consisting of a uniform carbon film deposited onto ceramic/alumina substrates for electrochemical and sensing applications.
