The present disclosure relates to a method for reducing or preventing colloids adhesion and/or fouling on a substrate in need thereof by forming a coating having a first layer that includes a polyphenol compound, and a second layer that includes a hydrophilic polymer having repeating units derived from one or more zwitterionic monomers, typically one or more betaine monomers, on the substrate. The present disclosure also relates to the coating made thereby and an article having the said coating.

A coating composition for application to a component or structure has cellulose acetate, a plasticizer with an antioxidant, a corrosion inhibitor with an antioxidant, a vegetable oil, and a stabilizer. The plasticizer is linseed oil. The corrosion inhibitor is canola oil. The vegetable oil is epoxidized soybean oil. The stabilizer is titanium dioxide. These components are intimately mixed together so as to form a solid mixture. The solid mixture is converted into a solid state and applied to the component or structure. The liquid state is then dried on the component or structure for a period of time.

A surface-treated fluidic channel is provided comprising a dispensing device that comprises a microarray of microchannels. The fluidic channel is made from metal and comprises a surface and a hydrophobic coating layer comprising a self-assembled monolayer of an organophosphorus acid adhered to the surface. A mesh nebulizer comprising a reservoir and a dispensing device comprising a microarray of microchannels is also provided. A metal surface layer is applied to the interior and exterior surfaces of the reservoir and dispensing device, and a hydrophobic coating layer comprising an organo-silicon or a self-assembled monolayer of an organophosphorus acid is adhered to the metal surface layer, usually on the exterior surfaces of the reservoir and dispensing device. A hydrophilic polymeric coating layer may be chemically bonded to and propagated from terminal functional groups on the hydrophobic coating layer on the interior surfaces of the reservoir and dispensing device.

The present invention relates to a film-forming dispersion comprising a functionalized polyamide and water.

An electronic device, according to various embodiments, may comprise: an outer housing comprising a front plate facing a first direction, a rear plate facing a direction opposite to the front plate, and a side member for surrounding a space between the front plate and the rear plate, wherein the side member protrudes toward the space and includes a protrusion having a first surface facing the first direction; an opaque layer disposed in the space so as to be parallel with the front plate and including a first portion located between the first surface and the front plate, wherein the first portion includes a second surface facing the first surface; an adhesiveness improvement layer formed on the second surface of the opaque layer and having a repetitive pattern; and a waterproof layer disposed between the adhesiveness improvement layer and the first surface and attached to the adhesiveness improvement layer and the first surface. Other various embodiments may be possible.
