Abstract:
The present invention aims to provide a decorative sheet exhibiting excellent heat-insulating performance, weather-resistant contact, and design with muted colors, and a decorative member including the decorative sheet. The present invention provides a decorative sheet having a lightness value of 55 or less and including: a base sheet; a decorative layer; and a surface protective layer, wherein the decorative layer contains a composite oxide containing at least manganese and has a thickness of 0.7 to 13 µm. The present invention also provides a decorative member including the decorative sheet.
Abstract:
The present invention relates to a method of enhancing hydrophilicity of a hydrophobic polymer material, comprising: pre-treating the hydrophobic polymer material, comprising treating the hydrophobic polymer material with a first atmospheric pressure plasma discharge in a first atmosphere comprising ammonia to obtain a pre-treated polymer material, and treating the pre-treated polymer material with a second atmospheric pressure plasma discharge in a second atmosphere in which an aerosol of a carboxylic acid is introduced. A substrate is provided as well, the substrate comprising a hydrophobic polymer material having a modified interface, wherein the modified interface comprises carboxylic functional groups grafted on the hydrophobic polymer material, the modified interface having a contact angle with water, which, measured after immersion in water at 20°C for 3 days, is at least 25° less than a contact angle with water of the hydrophobic polymer material.
Abstract:
The invention relates to a method for preparing a lubricated surface of an article to reduce the break-out force and sliding frictional force, comprising: providing one or more surfaces; applying a lubricant to at least one of the surfaces forming a coated surface, the lubricant including a compound selected from the group consisting of a perfluoropolyether, a functionalized perfluoropolyether, a polychlorotrifluoroethylene, a polysiloxane-based compound, and mixtures thereof; and exposing the coated surface to an ionizing gas plasma at atmospheric pressure.
Abstract:
The invention relates to a plastic from a group comprising polyethylene (PE), polypropylene (PP), polypropylene/ethylene-propylene-diene-rubber (PP/EPDM) or mixtures thereof, wherein the plastic is coated by a primer comprising a halogenized polyolefin, and the primer is coated by an elastic paint cured by polymerization using a radical reaction, wherein the plastic is an expanded plastic, wherein the paint prevents the penetration of moisture.
Abstract:
The invention relates to a method for surface treating a substrate (28) by means of an electrical corona discharge, wherein aerosols (5) are sprayed in the discharge area defined by an active gap formed between a corona electrode and the substrate (28) during the discharging, designed such that the aerosols (5) are sprayed substantially opposite the direction of gravity.
Abstract:
A method of applying a coating (17) of a thermoplastic material on a substrate (11) made of a polymeric material, wherein said thermoplastic material and said polymeric material are incompatible, comprising the following steps. Firstly, exposing the substrate and/or the powder to a plasma discharge (12) or the reactive gas stream resulting therefrom in order to obtain a plasma treated surface layer (14) introducing compatibility at the interface between substrate and coating. Secondly, laser cladding (15) the powder (16) on the substrate in order to form a coating on the substrate.
Abstract:
A porous substrate (12) is pretreated in a plasma field (20) and a functionalizing monomer is immediately flash-evaporated (22), deposited and cured (24) over the porous substrate in a vacuum-deposition chamber (10). By judiciously controlling the process so that the resulting polymer coating adheres to the surface of individual fibers in ultra-thin layers (approximately 0.02-3.O micrometers) that do not extend across the pores in the material, the porosity of the porous substrate (12) is essentially unaffected while the fibers and the final product acquire the desired functionality. The resulting polymer layer is also used to improve the adherence and durability of metallic and ceramic coatings.
