Abstract:
A producing method of a plasma polymerized film includes irradiating a composition containing at least one kind of radically polymerizable compound, and at least one of a polymerization initiator and a chain transfer agent with plasma.The plasma polymerized film is formed by polymerizing a composition containing at least one of a polymerization initiator and a chain transfer agent, and at least one kind of radically polymerizable compound by irradiation of plasma.
Abstract:
A method of plasma polymerisation of monomers for providing a cross-linked polymeric material, the method comprising: treating a monomer gas in a plasma, said monomer gas comprising one or more monomers selected from substituted benzenes, wherein said plasma is generated by a multiple phase AC supply or a DC supply at a plasma power density allowing a substantial portion of substituent groups of said substituted benzenes to be preserved.
Abstract:
Starting from hydrocarbons and/or fluorocarbons, glow polymerisate layers can be generated on a substrate by means of a high-frequency low-pressure glow discharge. Chemically stable layers are obtained if the glow polymerisate is subjected, after the preparation and with the exclusion of air, to an annealing process in an atmosphere of hydrocarbon and/or fluorocarbon monomers at temperatures between 100.degree. and 450.degree. C. for 1 to 10 hours, or if the substrate is heated to temperatures between 100.degree. and 450.degree. C. during the preparation of the glow polymerisate.
Abstract:
Thin, pinhole-free, adherent, colored polymeric coatings and articles are produced by plasma polymerization followed by a heat treatment. The polymer precursor is mixed with a dye or pigment and shaped into a self-supporting thin article or applied to a substrate. The coating or article is then polymerized under plasma conditions created by an applied electrical field. Subsequent heat treatment further cures the polymer and makes the coating adherent to the substrate.
Abstract:
A plasma polymerization process for the deposition of a dielectric polymer coating on a substrate comprising disposing the substrate in a closed reactor between two temperature-controlled electrodes connected to a power supply, maintaining a vacuum within the closed reactor, causing a monomer gas or a gas mixture of a monomer and diluent to flow into the reactor, generating a plasma between the electrodes, and varying and controlling the dielectric constant of the polymer coating being deposited by regulating the gas total and partial pressures, the electric field strength and frequency, and the current density. A monomer, such as a polar saturated or unsaturated nitrogen-containing compound, or a monomer and diluent, such as a saturated or unsaturated aliphatic hydrocarbon and nitrogen, can be polymerized to form a dielectric coating having a varying dielectric constant in accordance with this plasma polymerization process.
Abstract:
Apparatuses and methods are described that involve the deposition of polymer coatings on substrates. The polymer coatings generally comprise an electrically insulating layer and/or a hydrophobic layer. The hydrophobic layer can comprise fused polymer particles have an average primary particle diameter on the nanometer to micrometer scale. The polymer coatings are deposited on substrates using specifically adapted plasma enhanced chemical vapor deposition approaches. The substrates can include computing devices and fabrics.
Abstract:
Process for providing a polypropylene composition comprising a branched polypropylene in which a polypropylene with a melt flow rate MFR2 (230° C.) of more than 1.0 g/10 min is reacted with a thermally decomposing free radical-forming agent and optionally with a bifunctionally unsaturated monomer obtaining thereby the branched polypropylene,wherein the polypropylene composition has a F30 melt strength of more than 5.8 cN and a v30 melt extensibility of more than 200 mm/s.
Abstract:
Provided are a composition, with which a coating film including an ionizing radiation curable resin and metal oxide particles can be formed, wherein surface hardness is not decreased to be lower than surface hardness in the case where a composition includes only an ionizing radiation curable resin, and a laminate. An exemplary composition can include an ionizing radiation curable resin, metal oxide particles and a polyfunctional (meth)acrylate having a multi-branched structure. A laminate can be formed on a substrate and provided with a coating film made by the composition that includes an ionizing radiation curable resin, metal oxide particles and a polyfunctional (meth)acrylate having a multi-branched structure.
