Abstract

Microbial-induced corrosion (MIC) is a critical challenge, and its prevention is important in many industrial applications such as pipelines or marines. Protective coatings containing antimicrobial materials are being utilized to control the ferrous and nonferrous metals from MIC, and also to keep their esthetic appearance and structural integrity. Nanomaterials are the auspicious biocides for their remarkable antimicrobial inhibition action, especially metal or metal-based nanoparticles (NP) are utilized for their noteworthy inhibition efficacy against various MIC microorganisms in different environmental conditions. The mechanism of NP or their nanocomposite to protect a metal is to deliver extraordinary biocorrosion inhibition owing to their interaction with microbes or cells. This chapter involves an overview of different nanomaterials or nanocomposites that provide suppression of bacterial growth and show resistance to MIC. Different corrosive microbes and the attributed challenges to make NP are also discussed.
