The present invention relates to a surface cover for a body which can be brought into contact with a liquid, comprising: a layer which at least partly contains gas and which is designed and arranged such that at least some sections of a layer face facing the liquid contacts the liquid; a gas-permeable layer which is arranged on the gas-containing layer on a face that faces the body and is opposite the face facing the liquid or which is integrally formed with the gas-containing layer; and a gas-supplying device which is connected to the gas-permeable layer such that gas can flow from the gas-supplying device to the gas-containing layer through the gas-permeable layer. The invention also relates to an arrangement and a use.

Methods and apparatus for preparing a protective coating are described. In one example aspect, an apparatus for preparing a protective coating includes a chamber, a substrate positioned within the chamber configured to hold at least a target object, an inlet pipe configured to direct a monomer vapor into the chamber, and one or more electrodes configured to perform a chemical vapor deposition process to produce a multi-layer coating. The chemical vapor deposition process comprises multiple cycles, each cycle comprising a pretreatment phase and a coating phase to produce a layer of the multi-layer coating.

The present invention relates to a film comprising hydrophobically modified cellulose fibers in which cellulose fibers are bound to a modifying group at one or more members selected from anionic groups and hydroxyl groups, and an oil having an SP value of 10 or less. The film of the present invention can be utilized in the fields of materials for packaging containers for cosmetics and foods.

Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

A substrate treatment method includes a first gas treating step, a water-repellency treatment step, and a spraying step. In the first gas treating step, a first gas is supplied to the substrate inside the chamber in a state in which the inside of the chamber is decompressed. The first gas includes gas of an organic solvent. The water-repellency treatment step is executed after the first gas treating step. In the water-repellency treatment step, the inside of the chamber is in the decompressed state, and a water-repellent agent is supplied to the substrate inside the chamber. The spraying step is executed after the water-repellency treatment step. In the spraying step, the inside of the chamber is in the decompressed state, and a first liquid is sprayed over the substrate inside the chamber. The first liquid includes liquid of an organic solvent.

The present invention relates to an article having a surface coated with a nanostructured temporary super-hydrophobic film having a static contact angle with water of at least 140°, and comprising nanoparticles functionalized with a hydrophobic agent, wherein the functionalization of the nanoparticles with the hydrophobic agent has been performed before said nanostructured temporary super-hydrophobic film is coated on said surface. The surface of the article exhibits a static contact angle with water of less than 60° before being coated with the nanostructured temporary super-hydrophobic film. The treatment according to the invention can be used to provide an antirain function to optical articles having a hydrophilic surface.
