Pure carbon will greatly improve the thermal properties of graphene. Graphene is grown from a mixture of Carbon-12 (12C)and Carbon-13 (13C). The combination of these two isotopes will affect the properties of CVD grown graphene. The properties of graphene will improve when the nuclei is identical. With a nuclide data showing a natural abundance of 1.109%, our Isotopic 13C single-layer CVD graphene on copper foil product is made solely from Carbon-13 (13C).

Research indicates that pure 13C graphene exhibits better thermal conductivity than CVD grown graphene with a mixture of naturally occurring isotopes. The thermal conductivity of CVD graphene, grown using carbon-13 feedstock is as high as 2816 W/mK at 300K. It is used for studying the isotope effect on the thermal conductivity of graphene..

Carbon-13 (13C ) has a non-zero spin quantum number of ½ which can then make the structure of carbon-containing substances visible when using nuclear magnetic resonance. In contrast to Carbon-12 (12C ) which cannot be detected by NMR since it has zero net spin. It opens up a possibility to use NMR to study various phenomena such as structural defects as well as the effect of graphene functionalization. Isotopic 13C single-layer CVD graphene is produced from a purified isotope which makes this product desirable in research fields such as medical research where NMR is utilized.
