A polymerizable quaternary ammonium compound (QAC) including an acrylate group and a cationic group is provided. Specifically, the acrylate group is capable of polymerization so as to integrate the QAC into a macromolecular chain of a polymer through an addition polymerization for introducing antimicrobial and antiviral activities. For instance, the polymerizable QAC can be polymerized with a vinyl group monomer, an acrylate monomer, a silane monomer, an adhesion monomer and an emulsification monomer to form a synthesized polymer emulsion. The polymer emulsion can be further incorporated into a coating material to provide a transparent, water resistant, antimicrobial and antiviral waterborne coating on a substrate's surface.

The present invention provides an article having a water- and oil-repellent surface layer, as well as excellent water- and oil-repellent properties, abrasion resistance (resistance to abrasion by eraser), and slipperiness, said article being constituted from: a glass substrate; an underlayer formed upon the outer surface of the glass substrate and having a silicon oxide as the main component thereof; and a water- and oil-repellent surface layer formed upon the outer surface of the silicon oxide underlayer. The film density of the silicon oxide underlayer is 1.8-2.2 g/cm.sup.3. The water- and oil-repellent surface layer has, as the main component thereof: a fluoropolyether group-containing polymer having a hydrolyzable silyl group with a specific structure; and/or a cured product of a partially hydrolyzed condensate thereof.

Disclosed is a highly functional AF hard coating film, which includes a transparent substrate layer, a hard coating layer formed on the transparent substrate layer and composed of a compound including a structure having reactivity with an alkoxysilane group, and an AF coating layer formed on the hard coating layer and composed of a perfluoro compound containing an alkoxysilane group, and can exhibit high functionality, such as high hardness, high scratch resistance, anti-glare and anti-fouling, and is thus suitable for replacing an existing display tempered glass cover window or serving as a film for protecting tempered glass.

Surfaces are modified with polymeric or monomeric amic acids that also comprise one or more tertiary amine functional groups. The amic acids may provide benefits including hydrophilicity, soil resistance, and corrosion inhibition to the treated surfaces. Compositions and methods for treating surfaces are provided.

Methods of preparing surfaces of sample wells are provided. In some aspects, methods of preparing a sample well surface involve contacting the sample well with a block copolymer to form an antifouling overlay over a metal oxide surface of the sample well. In some aspects, methods of passivating and/or selectively functionalizing a sample well surface are provided.

The present invention provides an antifouling coating formed from a water-based coating composition comprising 0.1% by mass to 10% by mass of ultrafine silica particles having an average particle size equal to or less than 25 nm, 5% by mass to 50% by mass, relative to the ultrafine silica particles, of a zirconium compound which is at least one selected from zirconium chloride and zirconyl chloride, and 30% by mass to 99.5% by mass of water. In accordance with the present invention, it is possible to provide an antifouling coating that can maintain the antifouling performance and hydrophilicity and prevent corrosion of fins even under an environment with a large amount of contaminating substances, such as metal particles, in the air.

The present invention provides a surface-independent surface-modifying multifunctional biocoating and methods of application thereof. The method comprises contacting at least a portion of a substrate with an alkaline solution comprising a surface-modifying agent (SMA) such as dopamine so as to modify the substrate surface to include at least one reactive moiety. In another version of the invention, a secondary reactive moiety is applied to the SMA-treated substrate to yield a surface-modified substrate having a specific functionality.
