摘要： Anti-fouling coatings and associated systems and methods are generally described. In some aspects, a system comprises a substrate, a coating disposed on at least a portion of the substrate, and a fluid comprising one or more foulants, where the coating is configured to be in physical contact with the fluid during use. According to some embodiments, a full-spectral Hamaker constant associated with the coating and the fluid is relatively low (e.g., about 20 zj or less, about 10 zj or less), and the van der Waals (vdW) force between the coating and the one or more foulants is, therefore, correspondingly low. Under some conditions (e.g., high temperature and/or high pressure conditions), intermolecular interactions between the coating and the one or more foulants may he dominated by the vdW force, and a relatively low vdW force may reduce the likelihood of the one or more foulants adhering to and/or otherwise being deposited on the coating.

摘要： Composite anti-fouling coatings and associated systems and methods are generally described. In some aspects, a system comprises a substrate, a composite coating disposed on at least a portion of the substrate, and a fluid comprising one or more foulants, where the composite coating is configured to be in physical contact with the fluid during use. The composite coating may comprise a first region comprising a first material and a second region comprising a second material that is different from the first material. According to some embodiments, a full- spectral Hamaker constant associated with the composite coating and the fluid (i.e., based on average optical properties of the first and second materials of the composite coating) is relatively low, and the van der Waals (vdW) force between the composite coating and the one or more foulants is, therefore, correspondingly low. Under some conditions (e.g., high temperature and/or high pressure conditions), intermolecular interactions between the composite coating and the one or more foulants may be dominated by the vdW force, and a relatively low vdW force may reduce the likelihood of the one or more foulants adhering to and/or otherwise being deposited on the composite coating. By selecting materials for the composite coating that result in a relatively low full- spectral Hamaker constant, fouling of the composite coating may thus be reduced or even eliminated. In some cases, two or more materials with optical properties (e.g., refractive indices, frequency-dependent dielectric response values) that, when averaged, are substantially similar to those of the fluid across a spectrum of frequencies or wavelengths may advantageously be associated with a relatively low full- spectral Hamaker constant.

摘要： This invention relates to a novel application of liquid-infused surface materials (LISM) to at least a portion of one or more surfaces of razor components (e.g., frame, housing, clips, blade supports, blade body, blade edge, lubricating bodies, guard, handle, grip, button). If applied to a skin contacting surface of a component, the one or more LISM layers may generally be abrasion-resistant, long-lasting or non-erodible, desirably elevating shaving performance, such as glide, comfort, rinsing, and cleanliness, while also simplifying the manufacturing process.

摘要： The instant invention describes an anti-biofouling structure for placement onto structures or surfaces that are exposed to aquatic environments. Embedded within the anti-biofouling structure are agents that can diffuse out of the structure and prevent the formation and/or accumulation of plant and animal species build-up that creates biofouling. The instant invention also describes a system for preventing biofouling of an object stored in an aquatic environment which includes the anti-biofouling structure, and a protective cover element constructed and arranged to fit various structures, such as boat propellers.

摘要： A coating composition is provided for inhibiting growth of fungus and/or algae on a surface. The coating composition includes a dry film preservative and an antibacterial dry-film preservative comprising an immobilized isothiazolin-3-one derivative/zinc oxide complex. The amount of the antibacterial preservative comprising immobilized 1,2-isothiazolin-3-one derivative/zinc oxide complex and the dry film preservative contained in the coating composition is sufficient to inhibit or prevent the defacement of a surface exposed to the environment, when such defacement is due to growth of fungi or algae, or a combination of fungi and algae on a surface coated with said surface coating composition.

摘要： A coating film and a method for forming the same are provided. The coating film controls reduction in repellency of hydrophobic fine particles and increases rub fastness of the coating film. The coating film includes a ground layer containing thermoplastic resin (chlorinated polyolefin or acid modified chlorinated polyolefin, for example) and an upper layer containing hydrophobic fine particles (hydrophobic silica particle or silicone resin particle, for example) formed on the ground layer. Parts of the hydrophobic fine particles contained in the upper layer are buried in the ground layer.
