Abstract:
The present invention provides a multifunctional diffusion barrier comprising at least one organic polymer and a 2D graphene or 2D graphene derivative material, wherein it comprises a gradient concentration of the 2D graphene (derivative) material. It also relates to the method for preparing it. The multifunctional diffusion barrier of the invention can be used as a liquid and/or gas barrier, or as structural material, or as sealing material, or as a self-cleaning material or as protective material against UV radiation in aeronautical, automotive, marine or building field. In particular, the multifunctional diffusion barrier of the invention is particularly suitable in producing parts of aircraft such as a fuel tank, a fuel tank conduit and a gasket.
Abstract:
The invention relates to a method for preparing an optical system item having a non-zero radius of curvature and coated with an interference coating. Said method includes: a) providing a thermoplastic film coated with a multilayer interference coating containing at least one layer having a refractive index of greater than 1.65 and at least one layer having a refractive index of less than or equal to 1.65, at least one of the interference coating layers being a vacuum-deposited organic/inorganic layer, b) laminating said coated thermoplastic film, by means of an adhesive layer, onto an optical system item including a substrate, and c) recovering said optical system item, including a substrate coated with the adhesive layer, from the thermoplastic film and the multilayer interference coating.
Abstract:
The present invention has as an objective to improve the evacuation of a viscous liquid from a container, in particular when the viscous liquid is a condiment containing enzyme modified egg yolk. This objective has been achieved by internally coating a container with a vegetable oil containing an emulsifier having a HLB-value ranging from 1 to 12, prior to filling the coated container with the viscous liquid.
Abstract:
A method for the preparation of nanocomposite plastic materials includes coating thermoplastic polymer granules with sizes from 0.5 to 5 mm, using a physical vapor deposition (PVD) sputtering technique, with a coating layer from 1 to 100 nm of a material dispersible in a matrix of said thermoplastic polymer to form coated thermoplastic polymer granules, and thereafter plasticizing and injection moulding the coated thermoplastic polymer granules at high pressure into a closed mould.
Abstract:
An object of this invention is to provide a molded resin product having atmosphere of a quality product as a result of a stereoscopic pattern that is formed on the container surfaces by a simple method such as coating or vapor deposition. Another object of this invention is to provide a surface treatment process for laying a stereoscopic pattern of high quality on the resin surfaces. The molded resin product of this invention comprises a substrate made of a transparent resin, opaque coating film disposed on rear surface of the substrate except for an area set aside for a patterned portion, a transparent resin material disposed in the area set aside for the patterned portion on the rear surface of the substrate, and an opaque reflection coating or a half-reflective coating laminated to the transparent resin material. Under this configuration of the molded resin product of this invention, the patterned portion looks as if it pops up from the rear surface of the substrate. If a half-reflective coating is used, the pattern is visible through the half-reflective coating when the pattern is viewed from the rear surface of the lid of a molded resin product, thus giving atmosphere of high quality to the container.
