A complex of beta-cyclodextrin and graphene (CD-G) and a method of use of the complex in corrosion protection of the metal surfaces exposed to high saline concentrations. Composite laminates comprise CD-G, zinc (optionally magnesium) powder embedded in a resin matrix and adjacent to the metal, followed by polyurethane comprising a polymeric zinc chelator, followed by a hermetic sealant layer and finally by a hydrophobic self-cleaning fouling release layer as a topcoat. Optional managed stress of the laminated layers by temperature swings and mechanical vibration ensures resolution of local strain at the formative stage and not during functioning, producing defects that are healed during deposition of the next layer. More than 99% of the zinc and other toxic ions extracted from the metal and coating are intercepted by the selective chelator layer insulated under the sealer and fouling-release layers.

A self-healing, scratch resistant slippery surface that is manufactured by wicking a chemically-inert, high-density liquid coating over a roughened solid surface featuring micro and nanoscale topographies is described. Such a slippery surface shows anti-wetting properties, as well as exhibits significant reduction of adhesion of a broad range of biological materials, including particles in suspension or solution. Specifically, the slippery surfaces can be applied to medical devices and equipment to effectively repel biological materials such as blood, and prevent, reduce, or delay coagulation and surface-mediated clot formation. Moreover, the slippery surfaces can be used to prevent fouling by microorganisms such as bacteria.

A composition and method for a microtexture hydrophobic or superhydrophobic coating. The microtexture coating includes a coating layer disposed on a substrate with hydrophobic or superhydrophobic particles dispersed on top of or partially embedded in the coating layer to form an outer layer. The outer layer exhibits water repellant properties. Use of the microtexture coating permits large scale, durable hydrophobic or superhydrophobic coating applications. The microtexture coating is a useful for application on wind turbines, airplanes, solar panels, windows, or cooling systems.
