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.

Method for treating nanofiber material and composition of nanofiber material

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.

Environment sensor and conjugated polyene for manufacturing environment sensors

The present invention relates to a novel process of preparing branched polymers by cyclotrimerization and branched organic materials containing triaroylbenzene moieties as base structural unit. The polymerization is a simple one-pot reaction, strictly regioselective and highly functionality-tolerant giving oligomeric and polymeric polymers with high degree of branching (up to 100%) in high yields (up to 99%). The polymers are processible, easily film-forming, transformable (curable) into thermosets by heat or irradiation, and readily crosslinkable by UV irradiation to give patterns with nanometer resolution. The polymers of the present invention can be blend with a variety of macromolecules for general use. The polymers can be metallified utilizing organometallic acetylene as building blocks and ceramization of the patterns of the obtained polymers afford ferromagnetic ceramic patterns with high resolution.

Composite material, especially multilayer material, and adhesive or bonding material

A method for limiting the transmission of light through a material is disclosed. In the method, a layer composed of a hyperbranched polymer formed via a copolycyclotrimerization reaction is interposed between a light source and the material. Also provided is a method for emitting light comprising exciting the hyperbranched polymer. In addition, methods for limiting the transmission of light and for emitting light using hyperbranched polymers formed by homopolycyclotrimerization reactions are disclosed. A new class of hyperbranched polymers produced by copolycyclotrimerization is also disclosed.
