Abstract: The invention relates to composite materials having an optical effect, comprising at least one moulding which essentially consists of core/shell particles whose shell forms a matrix and whose core is essentially solid and has an essentially monodisperse size distribution, where a difference exists between the refractive indices of the core material and of the shell material, and at least one further material which determines the mechanical properties of the composite, and to a process for the production of the composite materials. The materials according to the invention exhibit a viewing angle-dependent colour effect with freely adjustable mechanical properties.

Abstract: The invention relates to the use of core/shell particles, the core of which essentially comprises a degradable polymer with an essentially mono-disperse size distribution and the shell of which forms a matrix, which can be pyrolysed to give a carbon matrix, for the production of shaped bodies with regularly-arranged cavities and the corresponding shaped bodies.

Abstract: The invention relates to the use of core/shell particles whose shell forms a matrix and whose core is essentially solid and has an essentially monodisperse size distribution and whose shell is bonded to the core via an interlayer and whose shell has thermoplastic properties for the production of mouldings having homogeneous, regularly arranged cavities, to a process for the production of mouldings having homogeneous, regularly arranged cavities, and to the corresponding mouldings.

Abstract: The invention relates to the use of core/shell particles whose shell forms a matrix and whose core is essentially solid and has an essentially monodisperse size distribution as template for the production of inverse opal structures, and to a process for the production of inverse opal-like structures using core/shell particles of this type.
