  • Patent number: 11932943
    Abstract: Various embodiments include a method for producing a structure with a cold gas spraying method comprising: providing a carrier with a carrier surface, to which the structure is to be attached by the cold gas spraying method by following a travel path; and providing an element with an element surface different from the carrier surface. The element is arranged in the travel path and/or the travel path is specified such that intersections of the travel path and/or interruptions of the structure are arranged on the element surface.

  • Patent number: 9018320
    Abstract: The present invention relates to a polymer which has an electronic dipole covalently bonded to the polymer structure. The polymer structure forming the basis of the polymer is in particular an elastomer which can be unbranched, or also branched or crosslinked. The present invention equally describes a method for bonding a dipole molecule to a corresponding polymer structure or elastomer structure. The polymer in accordance with the invention can be present as a pure substance or also as a mixture with any other polymers, preferably with further elastomers. Uses of the polymer or of the obtained polymer blend will equally be provided.

  • Publication number: 20060258802
    Abstract: The invention provides dispersions of rigid-chain conjugated polymers, processes for their manufacture and the use thereof for the manufacture of electronic components. The process according to the invention comprises the steps of a) preparing a solution of the polymer in a strong acid or in a liquid mixture comprising a Lewis acid; and b) introducing the solution prepared in step a) into an aqueous surfactant solution so as to form a dispersion of the polymer. Thus, the invention provides a dispersion of such a polymer in an aqueous or organic or aqueous-organic dispersion medium, wherein the size of the dispersed polymer particles lies in the range of 10 to 800 nm. The dispersions according to the invention may be used for the manufacture of a thin film of the polymer, in particular, for electronic components.

  • Patent number: 6764569
    Abstract: An adhesive system for forming reversible adhesive bonds includes at least one polymeric adhesive component comprising at least one of polyurethanes, polyureas, or epoxy resins and at least one additional component that includes a functional group that can be activated by the introduction of energy, such that a chemical reaction with the adhesive component takes place involving a partial breakdown of the adhesive component. Reversible bonding of articles and controlled parting of an adhesive bond between articles can be achieved with the adhesive system.
