Embodiments of the present invention involve the provision of a solid dispersion of a color-forming material in a hydrophilic polyurethane material. In particular, although not exclusively, the present invention relates to devices comprising foam, e.g., hydrophilic polyurethane foam and a color former. Also included in the embodiments of the present invention are methods comprising the use of the devices, and other subject matter.
Abstract:
The disclosure relates to a method for coating a substrate with a lacquer. First, the lacquer is uniformly applied to the substrate. Then, the solvent proportion of the lacquer applied to the substrate is reduced, and the coated substrate is exposed to a solvent atmosphere. In some embodiments, the lacquer is heated. The invention also relates to a device for planarising a lacquer layer.
Abstract:
A substrate treatment method is provided, which includes: a liquid film forming step of forming a liquid film of a treatment liquid on a front surface of a substrate; a hydrophobization liquid supplying step of supplying a hydrophobization liquid to a center portion of the front surface of the substrate for hydrophobizing the front surface of the substrate, while rotating the substrate; an inactivation suppressing step of suppressing inactivation of the supplied hydrophobization liquid on a peripheral edge portion of the front surface of the substrate simultaneously with the hydrophobization liquid supplying step; and a drying step of drying the substrate to which the hydrophobization liquid has been supplied.

Abstract:
Method for coating a plastics substrate with a functional layer, wherein (a) in a vacuum chamber, an organic UV absorber which comprises at least one chromophore and at least one reactive side chain is evaporated and (b) is brought into contact with at least one surface of the plastics substrate and excited with a plasma, or (c) is excited with a plasma and then brought into contact with at least one surface of the plastics substrate, whereby a functional layer comprising the UV absorber is formed on the surface of the plastics substrate, the plasma being ignited at a pressure of greater than 10−5 bar and less than 1.013 bar.
Abstract:
A process for producing polymeric films by applying a liquid composition onto a surface of a substrate under vacuum conditions in a vacuum chamber. The composition has a first component which is polymerizable or crosslinkable in the presence of a sufficient amount of an acid; and a cationic photoinitiator which generates an acid upon exposure to ultraviolet radiation, electron beam radiation or both to cause polymerizing or crosslinking of the first component. A gas which emits ultraviolet radiation upon exposure to electron beam radiation is introduced into the vacuum chamber. The composition and the gas are exposed to electron beam radiation to cause the cationic photoinitiator to generate an amount of an acid to cause polymerizing or crosslinking of the first component. The composition is exposed to both electron beam radiation and gas-generated ultraviolet radiation and cured.
Abstract:
An inkjet-based process for programmable deposition of thin films of a user-defined profile. Drops of a pre-cursor liquid organic material are dispensed at various locations on a substrate by a multi-jet. A superstrate that has been bowed due to a backside pressure is brought down such that a first contact of the drops is made by a front side of the superstrate thereby initiating a liquid front that spreads outward merging with the drops to form a contiguous film captured between the substrate and the superstrate. A non-equilibrium transient state of the superstrate, the contiguous film and the substrate then occurs after a duration of time. The contiguous film is then cured to crosslink it into a polymer. The superstrate is then separated from the polymer thereby leaving a polymer film on the substrate. In such a manner, non-uniform films can be formed without significant material wastage in an inexpensive manner.
Abstract:
The present disclosure provides a flexible graphite sheet and a method for fabricating the same and a composite structure for the same. The method for fabricating a flexible graphite sheet comprises steps of coating an augmenting solution on a first film to form a composite structure, and heating the composite structure such that the first film and the augmenting solution form a flexible graphite sheet, wherein the thermal conducting cross-section of the flexible graphite sheet is larger than the thermal conducting cross-section of the first film, and the thermal conductivity of the flexible graphite sheet ranges from 1200 to 6000 W/m° C.
Abstract:
Disclosed herein is a method of coating a catalyst support, in which a monolithic catalyst support provided therein with a plurality of longitudinally formed channels is quantitatively coated with catalyst slurry applied to post-treatment of exhaust gas, including the steps of: introducing catalyst slurry into a quantitative container whose bottom is vertically moved; moving a catalyst support to the top of a container such that the bottom of the catalyst support and top of the container are horizontally disposed each other; sealing the bottom of the catalyst support and the top of the container from the outside; moving the bottom of the container upward; and applying a vacuum to the channels of the catalyst support.
