Abstract:
The present invention concerns a process for finishing substrates made of plastic, laminated or wooden material, in particular polymethylmethacrylate (PMMA), between 10 micron and 1 cm thick, using paints with radical cross-linking induced by LED sources with wavelengths between 320 and 450 nm, and the elements obtained with this process.
Abstract:
The present Invention is a process for uniformly depositing nanomaterials having particles smaller than 1 micron (i e, nanoparticles) onto a surface of a base material (substrate or surface) The method substantially prevents the deposition on the base matenal of larger particles (contaminants or clusters of the nanoparticles) which are often mixed with the nanomaterials Maintaining deposition uniformity, controlling the amount of deposition, and the elimination of larger particles enhances the utility of nanomaterials, and by subsequent processing, enables the development of multifunctional composite materials (or other coated substrates) to be used in commercial applications In the present invention nanoparticles are applied to other base materials by substantially eliminating deposition of larger clusters or aggregates of nano-sized materials or other large impurities of other materials upon or in the base materials by positioning the base material within an upper portion of a deposition chamber.
Abstract:
The present invention has an object of providing a synthetic resin laminate that is usable for a transparent substrate material or protective material, has high thermoformability (pressure formability, thermal-bending formability), high insert moldability, and high surface hardness and/or impact resistance, and also providing a molded body formed by molding such a synthetic resin laminate. The synthetic resin laminate includes a polycarbonate-based substrate layer; and a resin laminated on one of, or both of, two surfaces of the polycarbonate-based substrate layer, the resin containing a specific (meth)acrylate copolymer resin and a specific polycarbonate resin. The polycarbonate-based substrate layer includes a polymer alloy and thus has a glass transition temperature (Tg) of 110 to 130°C. Thus, the resultant synthetic resin laminate has high thermoformability and high surface hardness.

Abstract:
The present invention is a process for uniformly depositing nanomaterials having particles smaller than 1 μm (i.e., nanoparticles) onto a surface of a base material (substrate or surface). The process is used to deposit any solid (nanoparticle) of any shape such as nanofibers, nanotubes, nanoclays (e.g., platelet shaped), nano-spheres, or irregularly shaped granules. The base material upon which the nano-particles are deposited can be made of any material. The method substantially prevents the deposition on the base material of larger particles (contaminants or clusters of the nanoparticles) which are often mixed with the nanomaterials. The amount of deposition and the range of particle sizes to be deposited can also be controlled by this method. Maintaining deposition uniformity, controlling the amount of deposition, and the elimination of larger particles enhances the utility of nanomaterials, and by subsequent processing, enables the development of multifunctional composite materials (or other coated substrates) to be used in commercial applications. In the present invention nanoparticles are applied to other base materials by substantially eliminating deposition of larger clusters or aggregates of nano-sized materials or other large impurities of other materials upon or in the base materials by positioning the base material within an upper portion of a deposition chamber.
Abstract:
The present invention relates to a method of coating fluorocarbon or hydrocarbon on the surface of a workpiece using atmospheric pressure plasma. More particularly, the present invention relates to a method of coating hydrocarbon or fluorocarbon on the surface of a workpiece using plasma generated under atmospheric pressure such that the workpiece can have a hydrophobic or super-hydrophobic surface.The method of coating a surface of a workpiece with fluorocarbon to be hydrophobic or super-hydrophobic according to the present invention comprises the steps of generating first atmospheric pressure glow plasma by supplying a reaction gas into a discharge space formed between a first electrode and a second electrode, the reaction gas containing hydrogen gas, fluorocarbon gas and inert gas, the first and second electrodes being connected to an RF power supply of an atmospheric pressure plasma generator; and approaching the workpiece to the first electrode downstream of a reaction gas flow passing through the discharge space, such that the plasma created in the discharge space is transferred into a space between the first electrode and the workpiece to generate a second atmospheric pressure glow plasma therein, whereby a fluorocarbon coating layer can be formed on the surface of the workpiece.
