We show that the roughness of polycrystalline nickel has a significant effect upon the homogeneity of large-area multilayer graphene films grown via chemical vapor deposition. Nickel foil serves as a substrate/catalyst for this multilayer graphene growth. By mechanical polishing nickel foils and reducing roughness from ~100 nm to ~10 nm, we have obtained graphene films with fewer defects and greater thickness uniformity. Mechanical properties were determined by bulge testing and bending measurements on microscale cantilevers. Films from polished foils are thinner and show higher burst pressures.
