Abstract

Ultra-thin graphene coating has been reported to provide considerable resistance against corrosion during short-term exposures, however, there is great variability in the corrosion resistance due to graphene coating in different studies. It may be possible to overcome the problem of hampered corrosion protection ability of graphene that is caused due to defective single layer graphene by applying multilayer graphene. Systematic electrochemical characterization showed that the multilayer graphene coating developed in the study provided significant corrosion resistance in a chloride solution and the corrosion resistance was sustained for long durations (~400 h), which is attributed to the multilayer graphene.

摘要

据报道，超薄石墨烯涂层在短期暴露期间能提供相当可观的抗腐蚀能力，然而，在不同研究中，由于石墨烯涂层，其耐腐蚀性存在很大差异。通过应用多层石墨烯，有可能克服因单层石墨烯缺陷导致的石墨烯防腐蚀能力受阻的问题。系统的电化学表征表明，该研究中开发的多层石墨烯涂层在氯化物溶液中具有显著的耐腐蚀性，并且这种耐腐蚀性能持续很长时间（约400小时），这归因于多层石墨烯。
