Abstract
The invention relates to the use of core/shell particles whose shell forms a matrix and whose core is essentially solid, is built up essentially from an inorganic material and has an essentially monodisperse size distribution and is connected to the shell via an interlayer, for the production of mouldings having homogeneous, regularly arranged cavities and particles in the cavities, to a process for the production of mouldings having homogeneous, regularly arranged cavities, and to the corresponding mouldings.

Use of core/shell particles whose shell forms a matrix and whose core is essentially solid, is built up essentially from an inorganic material and has an essentially monodisperse size distribution and is connected to the shell via an interlayer, for the production of mouldings having homogeneous, regularly arranged cavities and particles in the cavities.
Process for the production of mouldings having homogeneous, regularly arranged cavities and particles in the cavities, characterised in that
- a) core/shell particles whose core is essentially solid, is built up essentially from an inorganic material and has an essentially monodisperse size distribution and is connected to the shell via an interlayer, are converted into mouldings, preferably films, with application of a mechanical force and elevated temperature,
- b) one or more precursors of suitable wall materials are added,
- c) and the shell material is subsequently removed.
Mouldings having homogeneous, regularly arranged cavities, characterised in that the regularly arranged cavities essentially each contain one particle.
