“…Monomers containing tertiary amino groups, such as 2-dimethylaminoethyl methacrylate (DMAEMA) and 4-vinyl pyridine (4VP), have been extensively used in synthesizing antimicrobial polymers via surface graft polymerization (Figure 3) (Fan et al, 2005;Koplin et al, 2008;Yuan et al, 2009aYuan et al, ,b,c, 2010aYang et al, 2014). As an example of water-soluble polyamine, polyethyleneimine has not only been employed in preparing antimicrobial coatings (Milovic et al, 2005;Huang et al, 2008;Aguirre et al, 2017), but also been used as a corrosion inhibitor to protect steel (Braunecker and Matyjaszewski, 2007;Kugel et al, 2011;Rajasekar and Ting, 2011).…”

Biocorrosion has been considered as big trouble in many industries and marine environments due to causing of great economic loss. The main disadvantages of present approaches to prevent corrosion include being limited by environmental factors, being expensive, inapplicable to field, and sometimes inefficient. Studies show that polymer coatings with anticorrosion and antimicrobial properties have been widely accepted as a novel and effective approach to prevent biocorrosion. The main purpose of this review is to summarize up the progressive status of polymer coatings used for combating microbial corrosion. Polymers used to synthesize protective coatings are generally divided into three categories: (i) traditional polymers incorporated with biocides, (ii) antibacterial polymers containing quaternary ammonium compounds, and (iii) conductive polymers. The strategies to synthesize polymer coatings resort mainly to grafting antibacterial polymers from the metal substrate surface using novel surface-functionalization approaches, such as free radical polymerization, chemically oxidative polymerization, and surface-initiated atom transfer radical polymerization, as opposed to the traditional approaches of dip coating or spin coating.

“…In this sense, modifications of abiotic conditions through tidal cycles impose an external pressure on the development of microbial biofilms and their corrosive effect [27]. Although corrosion in marine environments has been extensively studied over the past few decades [21][22][23]28] and numerous strategies for mitigating corrosion have been proposed [29,30], the roles of the diversity and complexity of the microbial communities in MIC have not yet been fully understood [31]. At the same time, the development of biological characterization tools in the past few years has provided important insights into specific marine bacterial groups and their significance in biocorrosion under controlled laboratory conditions [32][33][34][35].…”

The effects of tidal cycles associated with the water level on the biocorrosion of stainless steel AISI 316L were studied. Steel coupons were exposed to different conditions of immersion in mesocosms fed by fresh seawater either continuously or in accordance with the periodicity of natural tides. After 5 and 15 weeks, all coupons were found to have undergone ennoblement associated with the formation of a biofilm. Analysis of the composition of the bacterial community using denaturing gradient gel electrophoresis (DGGE) revealed differences in the biological succession. After 15 weeks, exposure to the simulated tidal conditions resulted in biofilms with lesser bacterial richness; the corresponding rate of corrosion, as determined by weight loss, was about 40 times lower compared to the case for the continuous exposure to seawater. Phylogenetic analysis of selected DGGE bands and the inspection of biofilm morphologies revealed that the faster rate of corrosion was associated with the presence of iron-oxidizing Zetaproteobacteria and eukaryotic photosynthetic microorganisms. On the other hand, intermittent exposure to seawater resulted in the succession of microorganisms resistant to the stress associated with sudden environmental changes, which was associated with a low rate of corrosion.

“…From the above characterizations, they concluded that PEDOT is an excellent promising material for the inhibition of corrosion. 180 Kalendova 181 Electrochemically synthesized polypyrrole on Q235 steel with different dopants like oxalic acid, sodium dodecylbenzene sulfonate, toluene-psulfonic acid, sulfamic acid, or phytic acid was studied. The thickness of the coating was controlled to 40 mm.…”
