  • Three-dimensional scaffold structures with selectively functionalized polymer systems, their use and process for their manufacture
    Patent number: 11851674
    Abstract: A three-dimensional scaffold structure and a process for its manufacture. The scaffold structure has a polymer system obtainable by photostructuring a starting material containing precursor molecules or inorganic polymers thereof having an organically polymerizable radical with at least one C?C double bond, an inorganically polymerizable silane-based radical and a functional group or derivative thereof.
    Type: Grant
    Filed: November 14, 2019
    Date of Patent: December 26, 2023

  • Structured composite of matrix material and nanoparticles
    Patent number: 11578305
    Abstract: The present invention provides a composite which can be produced by photostructuring a photostructurable matrix material in a composite formulation to form a structured matrix with nanoparticles, where the refractive index of the composite with nanoparticles differs from the refractive index of the composite without nanoparticles at one wavelength, selected from the range from 150 nm to 2000 nm by less than 0.5, said composite being hierarchically structured and comprising at least one structural unit (I) of a selected thickness (i) and structural units (II) branching from said structural unit (I) of a selected thickness (ii), wherein the thickness (ii) at the branch-off points is at most half the thickness (i). In addition, the present invention provides an improved process for the preparation of a composite comprising photostructured matrix material and nanoparticles contained therein and the use of the composite.
