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.

Provided is an anti-fogging coated transparent article including an anti-fog film, the anti-fog film being a single-layer film containing a water-absorbent resin, a hydrophobic group, and a metal oxide component. The hydrophobic group is a chain or cyclic alkyl group having 1 to 30 carbon atoms, preferably a linear alkyl group having 6 to 14 carbon atoms, in which at least one hydrogen atom is optionally substituted by a fluorine atom. The hydrophobic group is bonded directly to a metal atom of the metal oxide component. The anti-fog film contains, for example, the metal oxide component in an amount of 0.01 to 60 parts by mass and the hydrophobic group in an amount of 0.05 to 10 parts by mass per 100 parts by mass of the water-absorbent resin. The water-absorbent resin is, for example, polyvinyl acetal.

A display device includes: a display panel configured to fold along a folding axis; and a protective member disposed on the display panel, wherein the protective member includes: a protective base layer; a hard coating layer including a polymer derived from a coating composition, wherein the hard coating layer is disposed on the protective base layer; and an antireflection layer including a high refractive index layer and a low refractive index layer disposed on the high refractive index layer, wherein the antireflection layer is disposed on the hard coating layer, wherein the coating composition includes a silsesquioxane-based resin, an oxetane-based resin, a photopolymerization initiator, and silica nanoparticles, and wherein a first weight of the silica nanoparticles is about 3 wt % to about 5 wt % based on a total weight of the coating composition.
