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.

Abstract:
A process for the production of a multi-layer composite comprising applying a coating layer from a pigmented coating composition A onto the back face of a transparent plastic film and then applying an NIR-opaque coating layer from a pigmented coating composition B, wherein the pigment content of coating composition A consists 50 to 100 wt.% of black pigment with low NIR absorption and 0 to 50 wt.% of further pigment, which is selected in such a way that coating layer A' exhibits low NIR absorption and that the multi-layer composite exhibits a brightness L* of at most 10 units, wherein the pigment content of coating composition B is either a pigment content PC1 consisting 90 to 100 wt.% of aluminum flake pigment and 0 to 10 wt.% of further pigment, which is selected in such a way that NIR-opaque coating layer B' exhibits low NIR absorption, or a pigment content PC2 comprising
Abstract:
The present invention is a process for uniformly depositing nanomaterials having particles smaller than lµm (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.
