| Abstract Scope |
Despite excellent barrier properties, pristine graphene coating doesn’t offer intrinsic antibacterial properties which play a vital role in bacterial adhesion subsequently causing biocorrosion. Here, we propose silver-coated graphene multilayers on nickel surfaces as an antibacterial coating that can effectively serve as corrosion-resistant and also prevents the onset of microbial adhesion. This study employs Desulfovibrio Alaskensis G-20 as a model organism and synthesis of the silver coating through pulse laser deposition on different nickel surfaces as a technologically relevant substrate against biocorrosion studies. Tafel analysis indicated ~2-fold and a 4-fold decrease in corrosion rate in silver-coated nickel and multilayer graphene nickel respectively for microbial exposure for 30 days. Observations from SEM and CLSM images suggested a significant reduction of microbial attachment in silver-coated samples thus contributing to the corrosion resistance mechanisms. The findings of these studies can be effectively utilized in biofilm prevention and establishing corrosion-resistant coating for various industry-specific applications. |
