A self-assembled film-forming composition for orthogonally inducing, with respect to a substrate, a microphase separation structure in a layer including a block copolymer, in the whole surface of a coating film, even at high heating temperatures at which arrangement failure of the microphase separation of the block copolymer occurs. The self-assembled film-forming composition includes a block copolymer, and at least two solvents having different boiling points as a solvent. The block copolymer is obtained by bonding: a non-silicon-containing polymer having, as a structural unit, styrene, a derivative thereof, or a structure derived from a lactide; and a silicon-containing polymer having, as a structural unit, styrene substituted with silicon-containing groups. The solvent includes: a low boiling point solvent (A) having a boiling point of 160 C. or lower; and a high boiling point solvent (B) having a boiling point of 170 C. or higher.

A process of fabricating the waterproof coating may include selecting a substrate, utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate, and optionally coating the substrate with a hydrophobic chemical agent and/or other chemical agents to create a surface with nanoscopic or microscopic features. The process may utilize an all solution process or controlled environment for fabricating self-cleaning and waterproof coating that prevent wetting or staining of a substrate, or may utilize a controlled environment.

An object is to provide a surface treatment liquid which can firmly bond, while coating the surface of a treatment target with an extremely thin film, a coating whose hydrophilicity is unlikely to be lowered even when the coating is brought into contact with fats and the like to the surface of the treatment target and a surface treatment method using the surface treatment liquid described above. In a surface treatment liquid containing a resin (A) and a solvent (S), as the resin (A), a resin is used which includes a constituent unit (a1) that includes an organic group including a quaternary ammonium cation group and having a sulfonic acid anion group at a terminal and that is derived from an N-substituted (meth) acrylamide, and includes a reactive silyl group in at least one of molecular chain terminals, the concentration of the resin (A) in the surface treatment liquid is less than 2 mass % and the pH of the surface treatment liquid is 4 or less.

Embodiments of a system, method and apparatus for a gear are disclosed. For example, a metallic gear hub can include an axis of rotation and metallic gear teeth. The metallic gear teeth can be smaller than a final gear teeth size of the gear. The metallic gear teeth can be co-planar with the axis. In addition, the metallic gear teeth can be non-orthogonal to the axis. A polymer layer can be located on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth. The polymer gear teeth can form the final gear teeth size of the gear.

The ionic liquid-based coating is a coating for both porous and nonporous materials. As non-limiting examples, a porous substrate coated with the ionic liquid-based coating may be used to disinfect and remove microorganisms from air and water, to provide an antimicrobial surface for preventing microbial contamination, or to enhance filtration efficiency of the porous material for airborne and waterborne particulate matter without increasing flow resistance. As a further non-limiting example, a nonporous substrate coated with the ionic liquid-based coating may be used to form a surface capable of self-disinfection from microorganisms contacting surface. The ionic liquid-based coating includes at least one ionic liquid, an adhesive, and at least one additive, which may be a disinfectant, a viscosity modifier, a pH buffer, a fragrance, or combinations thereof.

A process of providing an antibacterial coating to the surface of an article including the steps of applying a layer of an antibacterial precursor layer to the surface of an article to which an antibacterial coating is to be applied, wherein said antibacterial precursor layer is a precursor from which the coating is to be formed; and directing a neutral molecular hydrogen flux from a neutral molecular hydrogen flux emission source towards the surface of the article. Upon impact of neutral hydrogen molecules on molecules at or on the surface of an article, the bonds of the antibacterial precursor layer are selectively ruptured, and wherein the selectively ruptured bonds cross-link with themselves or with other chemical moieties at said surface or a combination thereof, resulting an antibacterial coating being formed on the surface of the article.

A vehicle body part including a support, an uncured sealer and an uncured primer, the uncured sealer being interposed between the support and the uncured primer, the uncured sealer and the uncured primer each including a compatible solvent, each compatible solvent having a log P.sub.ow value and an absolute value of a difference between the log P.sub.ow value of the compatible solvent of the uncured primer and the compatible solvent of the uncured sealer being equal to or smaller than 3.0. A method of forming a finished vehicle body part.

A thin oil film having parylene irregular dendritic-like columns extending from one side to another exhibits hydrophobic properties that can be used as a corrosion resistant coating or water-repellant, biofouling resistant surface. This parylene-in-oil layer can be paired with an adjacent layer of solid parylene that it overlays or underlays. The solid parylene cross polymerizes with the parylene dendrites, keeping them in place as well as the oil film. The parylene dendrites are fabricated by chemical vapor deposition (CVD) of parylene over the oil layer, the dendrites self-forming from the bottom to the top. Continued CVD over the dendrites can produce a top layer of solid parylene. Etching the solid parylene away can result in a water repellant, anti-biofouling surface.
