Nanoparticles-modified paints have shown huge potentials in a broad range of functionalities like surface protection, antifouling, corrosion resistance, self-cleaning, slip resistance, abrasion resistance among others. Consequently, they have been deployed for several industrial applications including pipelines, buildings, automobiles, electronics, among others. To further enhance their functionalities, paint industries have expended huge resources on research and development of advanced paints that are compatible and appropriate for today's hostile environments. Studies have been conducted on the utilization of degradable biocides such as zinc oxide nanoparticles (ZnONPs), silver nanoparticles (AgNPs), copper nanoparticles (CuNPs), photocatalytic-active nano-titanium dioxide nanoparticles (TiO 2 NPs), and silica dioxide nanoparticles (SiO 2 NPs) as major additives in paints. These additives are designed to offer improved surface protection against microbial, physical, and chemical deteriorations as well as enhanced scratch resistance. However, the addition of nanoparticles to paints is not without its demerits. Nanoparticles can agglomerate within the paint matrix leading to poor surface protection. In addition, the health and safety concerns from human exposure to emissions of nanoparticles must be adequately addressed. A few reported studies on the toxicology of nanoparticles are either short-termed or having variant or inconclusive results. This paper reports a critical assessment of nanoparticles as additives in paints. Extensive characterization of nanoparticle-modified paints is reported while the implications on the environment are also explored. New directions, targeting enhanced functionalities and lower toxicity, are proposed.

“…This observation can be attributed to the excellent adherence of the AgNP-inhibited coating to the metal surface and the consequent formation of protective film acting as a barrier between the metal and the corrosive environment. Although, the addition of nanoparticles minimizes the dissolution of metallic ions; however, it is not adequate to fully impede the reactive surface of the metal alloys from the acidic medium [11]. Consequently, AgNPs could act as a feasible inhibitor for metal alloys in the H 2 SO 4 medium.…”

“…This consequently makes the metals vulnerable and prone to corrosion during industrial application. The corrosive effects on the metallic surfaces can be minimized or controlled by using different approaches such as protective coating [6], alloying [7,8], cathodic protection [9,10], use of inhibitors [11,12], heat treatment [13], and environmental modifications [14].…”

Corrosion control of metals in aggressive environments has attracted a lot of attention due to its associated economic losses. However, most corrosion control techniques have not satisfactorily minimized these losses. This study examined the inhibition effects of silver nanoparticles (AgNPs) incorporated in gloss paint on corrosion of carbon steel and aluminium in 2.0 M H 2 SO 4 solution. The AgNPs were biosynthesized via green chemistry and characterized using Fourier Transform Infrared, UV-Vis spectrometer, and Transmission Electron Microscope. Samples of carbon steel and aluminium were uniformly coated with a thin layer of gloss paint mixed with AgNPs solution at five different concentrations of 0, 5, 10, 15, and 20 µg/ml. The inhibition efficiency of the AgNPs modified paint was conducted via gravimetric, gasometric, and potentiodynamic polarization analyses. Results of the gravimetric analysis revealed an increased weight loss with an increased period of exposure and decreased concentration of AgNPs in the paint. The corrosion rates for the mild steel and aluminium samples were 0.051 and 0.005 mmpy with inhibition efficiencies of 42% and 69%, respectively, when immersed in 20 µg/ml AgNPs-incorporated coating and exposed for 120 hours. Potentiodynamic polarization analysis revealed that the presence of AgNPs in the paint (as inhibitor) retarded the anodic dissolution by the formation of protective films on the mild steel and aluminium sample surfaces. The evolution of hydrogen gas from 20 µg/ml AgNPs-incorporated coating was significantly reduced by 81% and 14% for mild steel and aluminium, respectively, when compared with the control samples at 200 mins of exposure. These results revealed that incorporation of AgNPs into the gloss paint matrix minimizes the degradation due to corrosion of the mild steel and aluminium samples.

“…The latest research studies demonstrate that the incorporation of functional nanoparticles can combat and even prevent the corrosion occurrence and are also capable of enhancing the lifetime of the coating. Nanostructures such as silicon dioxide (SiO 2 ) [24,25], carbon nanotubes (CNT) [26,27], zinc oxide (ZnO) [28,29], zirconium dioxide (ZrO 2 ) [30], gold nanoparticles [31], silver nanoparticles [32], cerium dioxide (CeO 2 ) [33], titanium dioxide (TiO 2 ) [34], montmorillonite nanoparticles (MMT) [35], graphene oxide (GO) [36], and cerium oxyhydroxides (Ce-H 2 O 2 ) [37] are some examples of active agents that were investigated for their anti-corrosion properties.…”

The present review outlines the most recent advance in the field of anticorrosive coatings based on graphene oxide nanostructures as active filler. This carbonaceous material was extensively used in the last few years due to its remarkable assets and proved to have a significant contribution to composite materials. Concerning the graphene-based coatings, the synthesis methods, protective function, anticorrosion mechanism, feasible problems, and some methods to improve the overall properties were highlighted. Regarding the contribution of the nanostructure used to improve the capability of the material, several modification strategies for graphene oxide along with the synergistic effect exhibited when functionalized with other compounds were mainly discussed.
