| abstract |
The invention relates to a composite, which can be produced by photostructuring a photostructurable matrix material in a composite formulation, a structured matrix with nanoparticles thus being formed, wherein the index of refraction of the composite with nanoparticles differs from the index of refraction of the composite without nanoparticles at a wavelength selected from the range of 150 nm to 2000 nm by less than 0.5, the composite being hierarchically structured and comprising at least one structural unit (I) having a selected thickness (i) and structural units (II) deviating from the structural unit (I) and having a selected thickness (ii), the thickness (ii) at the branch-off points being at most half of the thickness (i). The invention further relates to an improved method for producing a composite that comprises photostructured matrix material and nanoparticles contained therein, and to the use of the composite. |
