Abstract:
Disclosed is a multilayer material in which at least two components are jointed to each other via an adhesive bond. The adhesive bond is formed by an adhesive or bonding layer containing nanofiber material in a matrix that is suitable as an adhesive.
Abstract:
Disclosed is a composition, in particular a dispersion, which contains nanofiber material in at least one organic matrix component, said nanofiber material being pre-treated in at least one method step for adjusting the physical properties of the composition.

Abstract:
In a method of producing a nanotube layer on a substrate by using a CVD process, the substrate is placed in a reaction chamber, which is flushed with a carbon-containing gas. Subsequently, the substrate is heated by an induction process to a temperature at which carbon from the gas phase is deposited on the substrate while forming nanotubes thereon.
Abstract:
The invention relates to a composite material made up of at least one ceramic layer or at least one ceramic substrate and at least one metallization formed by a metallic layer on a surface side of the at least one ceramic substrate.

Abstract:
The invention relates to a method for producing a field emission layer (3), preferably for luminescent screen applications, according to which in order to improve the serviceable life and long-time stability, a mixture consisting of a polymer (11) and carbon nanofibers (4), which are hardened in a low-oxygen, in particular, oxygen-free atmosphere at temperatures greater than 2000° C., particularly greater than 2500° C., preferably, approximately 3000° C., are applied to a cathode electrode (8) assigned to a cathode (1), and the cathode electrode (8), together with the carbon nanofibers (4)/polymer (11) mixture is heated to a temperature ranging from 300° C. to 500° C., preferably from 380° C. to 480° C., in particular, from 420° C. to 450° C. in an atmosphere at least containing oxygen, e.g. air, a consequence of the oxygen results in a pyrolysis and/or to a hardening of the polymeric base (7), and at least a portion of the carbon nanofibers (4) is exposed over at least a portion of the spatial extension of the carbon nanofibers (4), particularly at least over a portion of the length of the carbon nanofibers (4), in particular, at least over half the length.
