An undercoat agent including a block copolymer having a plurality of blocks bonded formed on a substrate. The undercoat agent contains a resin component that includes a structural unit having an aromatic ring and a structural unit having no aromatic ring, and the resin component includes a group which can interact with the substrate and does not include a 3 to 7-membered, ether-containing cyclic group; and a method of forming a pattern of a layer containing a block copolymer. The method includes applying an undercoat agent to a substrate to form a layer containing the undercoat agent; forming a layer containing a block copolymer having multiple blocks bonded on a surface of the layer containing the undercoat agent, followed by a phase separation of the layer containing the block copolymer; and selectively removing a phase containing at least one block of multiple blocks constituting the block copolymer.

Methods for forming a coating can include preparing a nanocomposite film including surface modified silicon dioxide nanoparticles, applying an oxygen plasma treatment to the nanocomposite film to form a treated nanocomposite film, and applying a fluorosilane solution to the treated nanocomposite film to form the coating. A coating can include a nanocomposite film including surface modified silicon dioxide nanoparticles, the nanocomposite film having an oxygen plasma treated surface, and a monolayer of a fluoro alkyl chain

A method is provided for producing an adhesive material (1) for a medical application such as a dressing. The method includes at least one step for coating a first surface (2b) of any substrate (4), called receiving substrate, using a layer of previously coated silicone on an anti-adherent liner (3). The silicone layer is an adhesive gel (2). The method further includes, prior to the coating step, a corona treatment step for the surface of the adhesive silicone gel that is intended to coat the receiving substrate (4).

Methods and apparatus for remote plasma processing are provided. In various embodiments, a reaction chamber is conditioned by forming a low recombination material coating on interior chamber surfaces. The low recombination material helps minimize the degree of radical recombination that occurs within the reaction chamber when the reaction chamber is used to process substrates. During processing on substrates, the low recombination material may become covered by relatively higher recombination material (e.g., as a byproduct of the substrate processing), which results in a decrease in the amount of radicals available to process the substrate over time. The low recombination material coating may be reconditioned through exposure to an oxidizing plasma, which acts to reform the low recombination material coating. The reconditioning process may occur periodically as additional processing occurs on substrates.

An expansion mount, electrode arrangement and a surface treater station include a mounting block with one or more clamps pivotally coupled to the mounting block to move between a connect position and a release position. When the mounting block is coupled to a surface treater, the one or more clamps are configured to engage the electrode in the connect position and disengage from the electrode in the release position.

A surface-treated carbon fiber having a mole ratio between a carboxyl group and an acid anhydride of 50:50 to 70:30 when measured by pyrolysis gas analysis, is manufactured by spraying a reactive gas that has been made into a plasma onto the surface of a carbon fiber and introducing a functional group into the surface of the carbon fiber.

A composition that is easily applied, clear, well-bonded, and superhydrophobic is disclosed. In one aspect, the composition includes a hydrophobic fluorinated solvent, a binder comprising a hydrophobic fluorinated polymer, and hydrophobic fumed silica nanoparticles. Also disclosed is a structure including a substrate coated with the composition, as well as a method for making the composition and a method of coating a substrate with the composition.
