Abstract Scope Despite significant choices for preventing the abiotic forms of corrosion effectively, there exists a lack of reliable protective coating for combating corrosion of metals exposed to aggressive microbial environments. Microbiologically influenced corrosion, a dangerous corrosion form has been reported to result in colossal monetary losses. Here we focus on developing protective coatings based on atomic layers of graphene using nickel as a technologically relevant metal and genetically tractable Desulfovibrio Alaskensis 20 as a model for sulphate reducing bacteria. Here we report an unusual behaviour of polycrystalline nickel surfaces modified with a single layer of graphene. We report that the nickel surfaces modified with graphene layer undergo an accelerated corrosion (12-fold higher) when compared to pristine form of nickel. We present a series of electrochemistry and microscopy tests to unveil this counterintuitive behaviour. We also present strategies to obtain rationally designed graphene coatings for effectively combating the MIC of nickel surfaces.
