Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

Anti-corrosion nanoparticle compositions include a carrier and a plurality of nonionic metal nanoparticles. The metal nanoparticles can be spherical-shaped and/or coral-shaped metal nanoparticles. The nanoparticles are selected so as to locate at the grain boundaries of a metal or metal alloy when the anti-corrosion composition is applied to the metal or alloy, thereby reducing or preventing intergranular corrosion of the metal or alloy.

The present invention provides multifunctional particulates that release one or more functional compounds in response to environmental triggers and whose external surface modification imparts secondary functionalities to a selected coating composition. For example, disclosed are hydrophobic particles having a smart release mechanism for anticorrosion compounds that release the anticorrosion compounds upon exposure to the local pH changes induced by corrosion processes. Formulations are disclosed for multifunctional smart particles having antimicrobial effects and protections as well.
