摘要 Polymer nanocomposite coatings (PNC) have been successfully utilized in hindering corrosion; scratching, biofouling, and so on. Inherent deficiencies accruable from usage of organic coatings in hindering or mitigating these environmental flaws are caused by their inherently porous micro-architecture which has defaulted in resisting attack of deteriorating elements, and damages from scratching, corrosion, surface abrasion, or wearing. Interestingly, these deficiencies have been overcome by PNC coatings. Potential techniques of enhancing impenetrability of organic coatings involve the inclusion of impermeable layered nanomaterials (NM). Amongst varying layered NM available, graphene (GN) (a twin-dimensional carbon layering), and nanoclay have presented unique behaviors capable of repressing surface faults due to their inherently elevated aspect ratios, superior mechanical and physical properties, in addition to their peculiar geometries and anti-microbial attributes. Hence, this paper elucidates recently emerging nanotechnological advancements in enhancing properties of polymer nanocomposite coatings (PNCs) including nano-silica and titanium dioxide coatings and mechanisms with special focus on graphene (GN), and nanoclay (PCN) coatings and mechanisms for effective surfacial mitigations and applications.
