Coating compositions are provided that eject droplets of condensed fluid from a surface. The coatings include a nanostructured coating layer and in some embodiments, also include a hydrophobic layer deposited thereon. The coating materials eject droplets from the surface in the presence of non-condensing gases such as air and may be deployed under conditions of supersaturation of the condensed fluid to be ejected. A heat exchanger design utilizing the coating is described herein.

Some variations provide a method of forming a transparent icephobic coating, comprising: obtaining a hardenable precursor comprising a first component and a plurality of inclusions containing a second component, wherein one of the first component or the second component is a low-surface-energy polymer, and the other is a hygroscopic material; applying mechanical shear and/or sonication to the hardenable precursor; disposing the hardenable precursor onto a substrate; and curing the hardenable precursor to form a transparent icephobic coating. The coating contains a hardened continuous matrix containing regions of the first component separated from regions of the second component on an average length scale of phase inhomogeneity from 10 nanometers to 10 microns, such as less than 1 micron, or less than 100 nanometers. The transparent icephobic coating may be characterized by a light transmittance of at least 50% at wavelengths from 400 nm to 800 nm, through a 100-micron coating.

A coating for a medical device or appliance may include a fluoropolymer and a polyimide. Such coatings may provide a lubricious exterior surface that facilitates insertion or displacement of a medical device in a body lumen. Some coatings that include a fluoropolymer and a polyimide may, among other functions and characteristics, provide increased strength and/or durability relative to some other coatings.

A method of manufacturing a dew formation preventing member having a super water repellent surface of the present invention comprises the steps of: mixing a particular paint and polytetrafluorethylene at a predetermined ratio; particulate painting the mixed paint on a substrate surface; and heat treating the particulate painted substrate. A method of manufacturing a dew formation preventing member having a super water repellent surface according to another aspect of the present invention comprises the steps of: immersing a substrate in an electro deposition paint, and applying a direct current to conduct electro deposition painting; heat treating the substrate that has undergone the electro deposition painting; and plasma treating the surface of the substrate that has undergone the electro deposition painting.

A method of forming a self-cleaning film system includes depositing a photocatalytic material onto a substrate to form a first layer. The method also includes disposing a photoresist onto the first layer and then exposing the photoresist to light so that the photoresist has a developed portion and an undeveloped portion. The method includes removing the undeveloped portion so that the developed portion protrudes from the first layer. After removing, the method includes depositing a perfluorocarbon siloxane polymer onto the first layer to surround and contact the developed portion. After depositing the perfluorocarbon siloxane polymer, the method includes removing the developed portion to thereby form the self-cleaning film system.

Relating to a sliding member for a fixing device having a resin coating film on a sliding surface, to provide a manufacturing method for the peeling member for the fixing device capable of forming a fine recessed groove as a lubricant reservoir on a surface of the resin coating film. The manufacturing method for the sliding member for the fixing device includes a coating film forming step of forming a resin coating film by drying a resin coating material after applying the resin coating material including a matrix resin on at least a sliding surface of the base material of the sliding member slid on the belt member, a coating film baking step of baking and hardening the resin coating film, and a recessed portion forming step of forming a recessed portion, which becomes a lubricant reservoir when the coating film baking step is performed, on the surface of the resin coating film, after the coating film forming step and before the coating film baking step.
