Composite materials and recording of 3D holograms

Optical nanocomposite materials with a nanoparticle concentration of up to 20 vol.% Are obtained for the first time in the world. %, Low light scattering in which is determined by the effects of self-organization.
 
The result was obtained in the framework of CRDF grant RE2-532 (2001) and published in patents:

Polymer nanocomposite having surface modified nanoparticles and methods of preparing the same, WO2006104689, Publication date: 2006-10-05 Inventor: DENISYUK IGOR Y (RU); WILLIAMS TODD R (US), US Patent; from. Polymer nanocomposite having a surface modified nanoparticles and methods of preparing the same, European Patent EP 1871842 DENISYUK IGOR Y (RU).
 
The properties of the developed nanocomposites with high contents of SiO2, ZnO, ZnS nanoparticles in a photopolymerizable matrix are studied, as well as photostimulated nanoparticle transfer processes, which ensure the formation of their three-dimensional distribution in the bulk of the material and the recording of 3D holograms.
