“…The polydopamine-modified g-C 3 N 4 /α-Fe 2 O 3 remained evenly dispersed for over 24 h. Very good corrosion protection was observed with the added polydopamine, and this was ex-plained in terms of strong interfacial bonding between the polydopamine and epoxy matrix, combined with very good barrier protection from the nanofillers. Other materials used to enhance the dispersion of g-C 3 N 4 in waterborne coatings or to enhance its mechanical properties as a filler include polyaniline formed on the surface of g-C 3 N 4 [203], molybdenum oxides, MoO x [205], and SiO 2 with TiO 2 [206]. Also, g-C 3 N 4 has been functionalized with ethylenediamine vapor to enhance its dispersion in a solvent-based epoxy [207].…”

Metals and alloys are essential in modern society, and are used in our daily activities. However, they are prone to corrosion, with the conversion of the metal/alloy to its more thermodynamically-favored oxide/hydroxide phase. These undesirable corrosion reactions can lead to the failure of metallic components. Consequently, corrosion-protective technologies are now more important than ever, as it is essential to reduce the waste of valuable resources. In this review, we consider the role of emerging 2D materials and layered materials in the development of a corrosion protection strategy. In particular, we focus on the materials beyond graphene, and consider the role of transition metal dichalcogenides, such as MoS2, MXenes, layered double hydroxides, hexagonal boron nitride and graphitic carbon nitride in the formulation of effective and protective films and coatings. Following a short introduction to the synthesis and exfoliation of the layered materials, their role in corrosion protection is described and discussed. Finally, we discuss the future applications of these 2D materials in corrosion protection.

“…Among the metal oxide nanofillers, nano-silica (SiO 2 ) [110][111][112][113], nano-titania (TiO 2 ) [114][115][116][117][118][119], nanoalumina (Al 2 O 3 ) [120][121][122], nano-zinc oxide (ZnO) [123][124][125][126][127], nano-zirconia (ZrO 2 ) [128][129][130][131], nano-cerium oxide (CeO 2 ) [132][133][134][135] and nano-iron oxide (Fe 2 O 3 and Fe 3 O 4 ) [135][136][137][138] are the very commonly used and detailed description on their nanofiller effect can be found elsewhere [109]. Recently, Steffi et al [139] developed a tertiary composite based on graphitic carbon nitride-Silica-Titania (gC 3 N 4 / SiO 2 /TiO 2 ) and tested its anticorrosion potential for mild steel in 3.5% NaCl. The synthesis of gC 3 N 4 , gC 3 N 4 /SiO 2 and gC 3 N 4 /SiO 2 /TiO 2 was achieved serially as presented in Figure 17(a).…”

Nanotechnology is a branch of science and engineering that involves the synthesis, modification, characterisation and application of nanoscale materials in diverse fields. They provide excellent surface coverage and are successfully used as corrosion inhibitors. However, most of the nanomaterials are not effective and require special treatments or modifications for proper anticorrosive activities. The present review article features the current approaches and practices that have been adopted to enhance the anticorrosive performance of nanoscale materials. One of the most growing interests in this direction is the use of covalently and non-covalently functionalised nanomaterials. The functionalised nanomaterials show remarkable improvement in corrosion protection performance. The covalently functionalised nanomaterials show better dispersibility and thereby better efficiency in aqueous electrolytes. In the anticorrosive formulations, nanomaterials avoid the penetration of corrosive species and thereby increase durability and corrosion inhibition. The nanomaterials in anticorrosive formulations also enhance weathering resistance, UV resistance, mechanical performance, thermal stability and hydrophobic property.
