The present invention relates to a hard coating film including a substrate and a hard coating layer provided on at least one surface of the substrate, in which the hard coating layer includes a cured product of a hard coating composition containing a fluorine-based UV-curable-functional-group-containing compound, dendritic acrylate, a conductive polymer, and a solvent, the conductive polymer being included in a specific amount, whereby the hard coating film is applicable to a flexible display device and can simultaneously exhibit hard coating performance and antifouling performance even in the form of a single layer that does not include a separate antifouling layer, and in particular, the high antifouling effect can be maintained even in the presence of variously changing environmental conditions, and to a window and an image display device using the same.

An antifouling coating composition including a copolymer including two or more moieties represented by Chemical Formula 1, and a linking group between the two or more moieties, a method of preparing the copolymer, and an antifouling film produced from the antifouling coating composition. ##STR00001## In Chemical Formula 1, the definitions of Ar, A, B, C, D, and m are as described in the specification.

A coated smooth surface of a substrate repels liquids and viscoelastic materials and can have anti-staining and anti-biofouling properties. The smooth surface can be coated by applying a chemical layer on the surface and a lubricant. Such coated surfaces are useful for use in toilets, urinals, or other devices for the processing of liquids and viscoelastic materials such as solid or semi-solid metabolic waste of human digestive system. Such coated surfaces can also be applied to windows for buildings or vehicles such as automobiles or camera lenses to repel liquids (e.g. rain), ice, frost, insect residues, and birds' feces.

The present invention is directed to environmentally benign coatings that can prevent fouling of submerged structures and surfaces in the marine environment. The coating is essentially a grease composition composed of an organic acids salt, mineral oil, a solvent and alkaline silicate. The sulfonate thickener is an oil soluble dispersing agent selected from a plurality of organic acids in a form of alkali metal salt or alkaline earth metal salt thereof, such as calcium sulfonate. Coating compositions of the invention can be used to coat surfaces, such that when such surfaces are exposed to or kept submerged in seawater they will prevent fouling of such surfaces when exposed to the marine environment for extended time.

A polypyrrole-graphene/polyurethane antifouling coating as well as a preparation method and an application thereof are provided. The polypyrrole-graphene/polyurethane antifouling coating includes component A and component B, wherein the component A mainly includes the following raw materials in parts by weight: 500 parts of group-hydrolyzable polyurethane prepolymer, 25-50 parts of bentonite, 25-50 parts of titanium dioxide, 60-120 parts of zinc oxide, 15-30 parts of talcum powder, and 15-30 parts of polypyrrole-graphene nanofiller; and the component B mainly includes the following raw materials in parts by weight: 5-7 parts of leveling agent, 5-7 parts of defoamer, 6-15 parts of chain extender, 10-25 parts of silane coupling agent, and 1-2 parts of catalyst. The two-component polyurethane coating of the present invention has relatively good adhesion, collision resistance and cracking resistance, and the antifouling property and the antifouling durability can be improved.

The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.

The present invention relates to a composition for peelable-coating-film formation including an elastomer and an amino-modified silicone oil, wherein a film formed from the composition for peelable-coating-film formation has a breaking strength of F.sub.B (N/20 mm) in a tensile test and a coating film formed from the composition for peelable-coating-film formation on a surface of an SUS304 plate has a peel adhesive force of F.sub.G (N/20 mm) in peeling from the SUS304 plate, F.sub.B/F.sub.G being 1.5 or larger.

Methods of protecting a surface include applying an inner polymer layer onto a surface. The inner polymer layer is impregnated with a biologically active chemical substance that protects the surface from biofouling-induced chemical, biological, and bio-proliferative damage. The inner polymer layer is an epoxy polymer. An outer polymer layer is applied onto the inner polymer layer. The outer polymer layer is impregnated with a biologically active chemical substance that protects the inner polymer layer from biofouling-induced chemical, biological, and bio-proliferative damage. The outer polymer layer is selected from the group consisting of polyurethanes and fluorourethanes.

Curable condensation compounds are obtainable by a reaction of non-end-equilibrated acetoxy group-bearing siloxanes with at least one alkoxy-functional polysiloxane, in the presence of a catalyst.
