  • Patent number: 10633869
    Abstract: Disclosed is a method to produce composite materials, which contain customized mixes of nano- and/or micro-particles with tailored electromagnetic spectral properties, structural elements based thereon, in particular layers, but also bulk materials including inhomogeneous bulk materials. In some embodiments the IR-reflectivity is enhanced predominantly independently of reflectivity for visible wavelength. The enhanced IR-reflectivity is achieved by combining spectral properties from a plurality of nano- and/or micro-particles of distinct size distribution, shape distribution, chemical composition, crystal structure, and crystallinity distribution. This enables to approximate desired target spectra better than know solutions, which comprise only a single type of particles and/or an uncontrolled natural size distribution.
