“…The higher fuel consumption results in an aggravation of CO 2 emissions and large economic losses. The annual global loss caused by marine biofouling was estimated to be $150 billion in 2016 [3,4]. The aquaculture industry, which in the USA is more than a $2 billion per year business, employing over 16,000 people, also requires non-toxic and long-lasting antifouling coatings.…”

An antifouling epoxy resin doped with natural clay nanotubes that are loaded with biocide or silver allowed extended protection against the proliferation of marine microorganisms. Compared to the 2-3 months of protection with antifoulant dichlorooctylisothiazolone (DCOIT) directly admixed into epoxy resin, the DCOIT release time of the halloysite formulations was extended to 12 months by incorporating biocide-loaded nanoclay in the polymer matrix. The protective properties of the epoxy-halloysite nanocomposites showed much less adhesion and proliferation of marine bacteria Vibrio natriegens on the resin surface after a two-month exposure to seawater than the coating formulations directly doped with non-encapsulated DCOIT. The coating formulation protection efficiency was further confirmed by twelve-month shallow field tests in the South China Sea. Replacing 2 wt.% biocide in the traditional formula with DCOIT-loaded natural environmentally friendly halloysite clay drastically improved the antifouling properties of the epoxy coating, promising scalable applications in protective marine coating. The antifouling property of epoxy resin was enhanced with silver particles synthesized on halloysite nanotubes. A natural mixture of MnO particles and halloysite could also be used as a nonbiocide additive to marine coating. The short-term White Sea water test of epoxy coating with 5% of Ag-halloysite composite of MnO-halloysite natural mixture showed no visible fouling.

“…Nevertheless, the costs associated with the increase of fuel consumption are much higher than the cleaning-associated costs [ 49 ]. Several strategies have been developed to control biofouling in marine equipment [ 50 ]. Copper has been applied and studied as a possible strategy for marine biofouling prevention for several centuries [ 51 ].…”

Biofilms are structures comprising microorganisms associated to surfaces and enclosed by an extracellular polymeric matrix produced by the colonizer cells. These structures protect microorganisms from adverse environmental conditions. Biofilms are typically associated with several negative impacts for health and industries and no effective strategy for their complete control/eradication has been identified so far. The antimicrobial properties of copper are well recognized among the scientific community, which increased their interest for the use of these materials in different applications. In this review the use of different copper materials (copper, copper alloys, nanoparticles and copper-based coatings) in medical settings, industrial equipment and plumbing systems will be discussed considering their potential to prevent and control biofilm formation. Particular attention is given to the mode of action of copper materials. The putative impact of copper materials in the health and/or products quality is reviewed taking into account their main use and the possible effects on the spread of antimicrobial resistance.

“…Many researchers suggest that drugs can perform just as well as green corrosion inhibitors especially since they are usually synthesized from natural products (Pathak & Mishra, 2013). Drugs are often chosen as corrosion inhibitors due to the fact that they contain oxygen, nitrogen and sulphur in their organic molecules, they are not harmful to the environment and they are easy to produce and purify [25]. Artemether is a derivative of artemisinin wherein the lactone group has been converted to a lactol methyl ether corresponding to it.…”

“…Artemether is a drug with chemical formula C16H26O5 commonly used in combination with Lumefantrine (benflumetol) to treat malaria which cannot be treated using chloroquine. It is on the World Health Organisation's list of essential medicines and is considered one of the safest and most effective medicines [25][26][27][28] Lumefantrine is also referred to as co-artemether. It is a drug with chemical formula C30H32Cl3NO.…”

In this study, electrochemical and structural pitting effect of Artemether/Lumefantrine inhibitive drug was examined as a corrosion inhibitor for mild steel in 0.625M sodium chloride (NaCl) medium using both weight loss and potentiodynamic polarisation method. The effect expired drug was assessed with thermodynamic parameters from temperature variation and adsorption mechanism. Surface morphological assessment was also carried out using scanning electron microscope (SEM) and energy dispersive x-ray spectroscopy (EDS) analyses. The results obtained shows that artemether/lumefantrine inhibits the corrosion of mild steel in 0.625M salt solution fairly well with an inhibition efficiency of up to 75% at 298 K at 20ml of the inhibitor. The inhibition efficiency reduced with increase in temperature but increased with increase in inhibitor concentration which suggests that the inhibition efficiency is inversely proportional to temperature but directly proportional to concentration. It operates with the mixed inhibition method since both the cathodic and anodic reactions were affected by the addition of the inhibitor. Langmuir adsorption isotherm best matches the behaviour of the inhibitor in the study with a minimum correlation coefficient of 0.975.
