A method of coating a substrate includes the steps of: (i) providing a suspension of dye and a binder in a solvent, wherein the ratio of dye to binder is greater than 40 wt % and the dye is uniformly dispersed in the solvent; (ii) spray-coating the suspension onto the substrate with the majority of the solvent evaporating during the spray coating step to result in a coating of dye and binder on the substrate having a density of up to 0.75 gcm-3; and (iii) continuing step (ii) until the coating thickness is at least 30 micrometres; wherein the dye does not include any carbon nanotubes.

The present application relates to a method for preparing a barrier film. The present application can provide a method for preparing a barrier film having excellent barrier characteristics and optical performances. The barrier film produced by the method of the present application can be effectively used not only for packaging materials of as foods or medicines, and the like, but also for various applications, such as members for FPDs (flat panel displays) such as LCDs (Liquid Crystal Displays) or solar cells, substrates for electronic papers or OLEDs (Organic Light Emitting Diodes), or sealing films.

A method of forming a biocompatible or biologically inert article for use in an application in which the article will make contact with at least one tissue, organ, or fluid within a human or animal body is provided. The method generally comprises providing an article having an external surface; selecting chemical precursors; using a means to direct one or more chemical precursors towards or to apply such chemical precursors to the external surface; activating the chemical precursors by exposing said precursors to atmospheric pressure plasma; and grafting and/or cross-linking the chemical precursors to form a solid coating adjacent to the external surface of the article.

The invention relates to the application of a coating to a substrate in which the coating includes a polymer material and the coating is selectively fluorinated and/or cured to improve the liquid repellance of the same. The invention also provides for the selective fluorination and/or curing of selected areas of the coating thus, when completed, providing a coating which has regions of improved liquid repellance with respect to the remaining regions and which remaining regions may be utilized as liquid collection areas.

A reflection-reducing layer system is disclosed. In an embodiment, the system includes a refractive index gradient layer including an inorganic material and an organic material in a spatially varying composition, wherein the refractive index gradient layer has a refractive index which decreases in a growth direction and an organic layer arranged above the refractive index gradient layer, the organic layer having a surface including a nanostructure.

Coatings, devices and methods are provided, wherein the contacting surface of a medical device with at least one contacting surface for contacting a bodily fluid or tissue, wherein long-lasting and durable bioactive agents or functional groups are deposited on the contacting surface through a unique two-step plasma coating process with deposition of a thin layer of plasma coating using a silicon-containing monomer in the first step and plasma surface modification using a mixture of nitrogen-containing molecules and oxygen-containing molecules in the second step. The two-step plasma coating process enables the implantable medical device to prevent both restenosis and thrombosis under clinical conditions. The invention also relates to surface treatment of metallic and polymeric biomaterials used for making of medical devices with significantly improved clinical performance and durability.
