2 M U L T I F U N C O A T Multi-functional coatings for polymeric solar thermal collectors AVENTA - solfanger Before Dekkplate, polykarbonat Absorbator, PPS Mål 1: Anti-soiling and antiabraisive surface properties Easy-to-clean Adequate service life Lotus effect Afte r Mål 2: Coloured, spectrally selective coatings on polymeric absorbers Increase efficiency Colours => Esthetics Source: Preuser, 2002 CONSORTIUM PARTNERE National Institute of Chemistry, Ljubliana, Slovenia COLOR, HELIOS Group; Slovenia AVENTA AS, Norway MÅL Develop innovative, multi-functional, energy efficient and competitive coatings for polymeric collectors suitable for solar thermal systems for buildings' roofs and facade integration. 2

3 Termiske solfangere Prinsipp Væske / vann / vann-glykolblanding solfanger solvarmeanlegg AVENTA S CONTRIBUTION, MULTIFUNCOAT Specify frame conditions, substrate=absorber; Prototype testing (in-lab / in-field) Full-size application of paint coatings Install demo system(s) (in 2011) Performance, marked and cost analysis 3

4 SURFACE PROPERTIY I : SPECTRAL SELECTIVITY - High solar absorptance - Low thermal emittance - Additional wish: other colors than black - Selectivity criterion = ( s - T ) > 50 %. TISS paints; Source: Orel,

5 THICKNESS INSENSITIVE SPECTRALLY SELECTIVE (TISS) PAINTS resin binder (silicon, polyurethane, fluoropolymer) solvents pigment (black or colored) metallic pigment (Al-flakes) hardener (isocyanates, melamine-formaldehyde) Literature: Orel et al., Silicone-based thickness insensitive spectrally selective (TISS) paints as selective paint coatings for coloured solar absorbers (Part I), Solar Energy Materials & Solar Cells 91 (2007) Orel et al., Selective paint coatings for coloured solar absorbers: Polyurethane thickness insensitive spectrally selective (TISS) paints (Part II), Solar Energy Materials & Solar Cells 91 (2007)

6 SURFACE PROPERTIES II : ANTI-SOILING & ANTI-ABRASIVE Hydrophobic & oelophobic properties = antisoiling Enhance abrasion resistance Easy-to-clean (reflected in high water and oil contact angles) Adequate service life (~25 years) Lotus effect Literature: Jerman I. et al., The effect of polyhedral oligomeric silsesquioxane dispersant and low surface energy additives on spectrally selective paint coatings with self-cleaning properties, Solar Energy Materials & Solar Cells 94 (2010) Jerman I. et al., Polyhedral oligomeric silsesquioxane trisilanols as pigment surface modifiers for fluoropolymer based Thickness Sensitive Spectrally Selective (TSSS) paint coatings, Solar Energy Materials & Solar Cells 95 (2011)

7 POLIHEDRAL OLIGOMERIC SILSESQUIOXANE (POSS) as low surface energy additive: Monofunctional POSS: IB8 T8 POSS, PF8 T8 POSS Multifunctional POSS: AP2IO6 T8 POSS, AP2IO4PF2 T8 POSS 7

8 Application in facades = visible architecture Increase attractiveness / flexibility for architects, planners, building owners Polymeric collector: light-weight, easy handling, designed as building module; reduce solar polymer processing techniques => large cost-reduction potential; 8
