The work on development of spectrally selective paints with company COLOR was successfully upgraded with the cooperation with a Norway firm AVENTA (producer of polymeric solar thermal collectors) which resulted in international project MULTIFUNCOAT in the frame of MATERA ERA-NET. Research work was started at the beginning of 2009 under the coordination of Boris OREL. First coatings on AVENTA's materials were succesfully applied; reports were given at »IEA Task 39« meetings.

COBISS.SI-ID: 4118042Research work in the frame of INNOSHADE project was continued under the leadership of Boris OREL, head of Slovenian part of project. One working group meeting was hosted by National Institute of Chemistry in January 2009. Group was very active in research on new materials for new types of electrochromic devices with a special note on sol-gel elelctrolytes and counter electrodes. In frame of this project several bilateral cooperations started and will result in applications for new projects.

COBISS.SI-ID: 4178714The subject of this invention is a sol-gel procedure for the preparation of anticorrosion coatings for solar collectors, prepared from cermets applied on metals. Core of this invention are processes for the preparation of ultra thin coatings, i.e. from 0.5 to 500 nm, which do not deteriorate optical properties of solar selective surfaces. The coatings were prepared with mixing of at least one mercapto silane with, another silane in organic solvent with water and acid. So protected absobers have excellent anticorrosion stability, that is more than 20 days in slat spray chamber.

COBISS.SI-ID: 4235290Black and coloured (red, green, blue) paints were prepared for use as thickness insensitive spectrally selective (TISS) paint coatings for solar facade absorbers on the basis of polyurethane binder. A low emittance of the paints was achieved by using low-emittance aluminium flake pigments, while black pigment was added to adjust solar absorptance. TISS paint coatings combine the advantages of paints (longevity and chemical resistance, variety of colours and simple application) with their spectral selectivity.

COBISS.SI-ID: 2892314Patent application describes the synthetic procedure of organophillic zinc oxide – ZnO nanoparticles and nanowires in various diols and the preparation procedure of their nanocomposites with poly(methyl methacrylate) - PMMA with the polymerization of MMA in bulk. ZnO nanofillers are applicable: as semiconductive additive to PMMA for various electronic applications; as visible and UV light converters in PMMA nanocomposites for solar technique; as UV absorbers and visible light stabilizers of transparent and nontransparent PMMA nanocomposites and in coating applications based on PMMA.
