  • 1. BIONIC TECHNOLOGY BV Invisible particles engineered to visible high-performance 2008-11 Coatings Bionic Technology BV Page 1
  • 2. Bionic Technology produces inorganic ceramic nanoparticles with homogeneous size – in industrial scale Elements can get new material properties only in nanoscaled sizes under 40 nm, e.g. electrical and magnetic properties nanoparticle E. coli bacteria house dust mite housefly 10-9 10-8 10-7 10-6 10-5 10-4 10-3 10-2 10-1 1 1 nm 1 µm 1 mm 1m molecule influenza virus blood cell tick hamster 2008-11 Coatings Bionic Technology BV Page 2
  • 3. Nano is an invention of nature Gecko Butterfly Efficient grip Colour brilliance without colour Nautilus Nacre is light, hard and Resistant to corrosion Lotus Shark Non-wetting surface Laminar Streaming by placoid flakes Quelle der Bilder: http://de.wikipedia.org 2008-11 Coatings Bionic Technology BV Page 3
  • 4. Nanotechnology: People are using it a long time Egyptian ink based on carbon particles Nanoscaled gold in coloured glass windows Opalescent soap bubble created by interference of nanometer thin films Source pictures: http://de.wikipedia.org 2008-11 Coatings Bionic Technology BV Page 4
  • 5. Production of nanoscaled particles 1. Synthesis of precursors 2. Crystallization 3. Cleaning step 4. Surface modification 5. Suspension Production 2008-11 Coatings Bionic Technology BV Page 5
  • 6. Innovative Coatings for Easier Cleaning 2008-11 Coatings Bionic Technology BV Page 6
  • 7. Nano-Effect After applying on smooth surfaces the nanoparticles organize themselves in a layer and combine with the surface. Hydrophobic surface Untreated Surface of the surface substrate On smooth surfaces they cross-link with the surface. The result is that e.g. on hydrophilic surfaces, liquids can run of like pearls and take away dirt particles. On sucking materials like textiles or wood, the coating material infiltrates the pores and covers each fiber. Moitsture and dirt particles can‘t permeate into the fibers because of the hydrophobicity, and run of like pearls. Nano-components Textile fibers Hydrophobic stone Appearance, breathability and grip of all treated materials remain the same. Hydrophobic textile 2008-11 Coatings Bionic Technology BV Page 7
  • 8. Hydrophobicity On hydrophobic surfaces, water runs off like pearls. A dimension for hydrophobicity on smooth surfaces is for example the contact angle. The angle build by a liquid drop on the surface to this surface is called contact angle. A surface is called hydrophobic when the contact angle is above 90° compare to water. Measurement of a contact angle (Kontaktwinkel) Waterdrops run down and take The contact surface for dirt This surface is not hydrophobic and away dirt particles on inclined particles is extremly reduced by has no microstructure. It is more surfaces. the microstructure of the surface. moistened by water, and dirt particles can adhere. 2008-11 Coatings Bionic Technology BV Page 8
  • 9. Hydrophobic coatings for glass, ceramic, metal and plastic surfaces Products for Glass & Ceramic Product for Plastic Properties Products for Metal  Hydrophobic and oleophobic coatings, waterdrops run off like pearls  Easy-to-clean-Effect Examples (Outdoor glass (Indoor glasses & (car glass) (alloy wheel rims) (chrome-stainless steal) (diverse plastics) applications) ceramic) 2008-11 Coatings Bionic Technology BV Page 9
  • 10. Anti-Fingerprint- and Non-Stick-Coating Products for Stainless Steel Non-Stick-Coating Antifingerprint-Effect  Non-Stick-coating for baking dishes e.g. with continuous heat resistance at 250°C  Transparent colourless lacquer  Excellent release of sugary bakery product  Fingerprints can be removed very easy  Excellent resistance to dish detergents  Hydrophobic coating, easier cleaning  Suitable for applications with food contact (requirement: completely cured coating!) Attention: Product only for industrial application Please contact us! Attention: Product only for industrial application! Please contact us! 2008-11 Coatings Bionic Technology BV Page 10
  • 11. Photocatalytic self-cleaning coating for glass and plastic surfaces O2 H2O2 Product for Glass UV-Light HO*  Especially suitable for facades, weather side, TiO2 e- + h+ because the photocatalysis need water in H2O sufficient quantity  Improvement of light efficiency  The surface tension against condensation water is increased above the air/water-value, hence e- : elektron results a total flowing of the condensation water. h+ : hole Photocatalysis-Process  Titanium dioxids is a semiconductor, UV-light generates electon-hole-pairs, that diffuse to the surface  Particularly the holes have a high oxidation effect, they turn water (H2O) into OH-radicals.  These radicals generate hydrogen peroxide together with oxigen  Organic substances can be decomposed 2008-11 Coatings Bionic Technology BV Page 11
  • 12. Hydrophobic coatings for textiles and leather Products for textiles and leather  Water-based or solvent-containing impregnation for Without ohne textiles and leather  Moisture penetration and re-soiling is extremely reduced Mit Nanoresist® TE 10 With Bionic Technology  washing-resistant impregnation for cotton and blended fabrics Examples 2008-11 Coatings Bionic Technology BV Page 12
  • 13. Hydrophobic coatings for wood, stone and lacquer Product for Stone and Wood  Breathable, water- and dirt-repelling  Multifunctional for open-pored, sucking undergrounds Products for Lacquers  2-Component-Systems  Adherences of dirt, insects, bivalves, barnacles, algae and contaminants are reduced Examples (Car finish) (Boat finish) (Stone & Timber) 2008-11 Coatings Bionic Technology BV Page 13
  • 14. Antibacterial active products Product for shoe interior  Shoe deodorant for neutralisation of unpleasant smell  avoids smell-generating bacteriae and fungi  Containing silver particles that avoid a new culture of bacteriae  Comfortable fresh smell by special fragrances  The effective period can be elongate by repeating the application  Biocide-registration number N-33097 Handle biocides with care. Apply biocides safely. Read the labelling and product informations before use. 2008-11 Coatings Bionic Technology BV Page 14
  • 15. Biocide hydrophobic coatings Product for textiles and leather  Water-based impregnation for textiles and leather with antimicrobial effect  Silver particles generate the antimicrobial effect  Biocide-registration number N-33365 Kontrollprobe mit 1244 Kolonien Bakterizide Eigenschaft im Nährmedium Product for Stone and Timber Examples  Water-based impregnation with fungicidal and antibacterial effect for timber  Suitable for nearly all kind of timber  Nanoscaled silver generates the antibacterial and fungicidal effect (Timber & Stone) (Textiles & Leather) 2008-11 Coatings Bionic Technology BV Page 15
