Growing graphene from refined palm oil, defect-free
Known as the strongest material on earth, graphene has a bright future prospect especially in batteries with the ability to charge an iPhone within seconds. However, scientists over the World are still hard at work to look new, more efficient ways to synthesis graphene. In UTM, our team demonstrated defect-free large-area mixed mono-and bi-layer graphene synthesis using refined cooking palm oil (a.k.a your household cooking oil) on nickel (Ni) via thermal chemical vapor deposition for the first time! The coverage of graphene on nickel, although not as high as those reported, we still manage to achieve a respectable coverage of 65%. Furthermore, the team manage to introduction some pre-treatment and post-rapid cooling to improve the uniformity and suppress the defect formation. This work provides an alternative approach towards a development of less expensive growth technology using safe, easily obtained, low value raw carbon-containing precursor.
