Bridge between companies and research institutes Invest in high risk projects Invest in products with large market potential Increase growth and create more jobs Active follow up 114 high-tech projects 3 billion DKK Environment, Bio/Medico, IT, Food, Production and Construction

6 Injection moulding process Nanostructures Free form surfaces

7 Nanostructured surfaces Structural colors Self-cleaning surfaces the Lotus effect Anti-fogging surfaces Anti-reflective Anti-stiction Tactile

8 Structural colors, inspired by nature (Butterfly wings) Left: Cymothoe Sangaris butterfly from Central Africa. The colors are a result of the nanostructures in the surface. Right: The surface of the butterfly wing is shown in the scanning electron microscope image. Nazum, MEng. Thesis, Univ. Southampton, 2007

9 Structural colors, colors from photonic crystals

10 Nanoimaging Atomic Force Microscopy (AFM) Image of stamp SEM Image of stamp pillar size 450 nm, period 700 nm AFM Image of imprint

11 Structural colors, applications The color patterns on the LEGO toys can be casted directly in the plastic material no need for adding decorative colors. The advantages are: Only well-known materials are used Simplified products Less transport to subcontractors

12 Self-cleaning surfaces the Lotus effect Left: Close-up of a water droplet on a lotus leaf. The droplet is not wetting the structured lotus surface and the droplet can easily roll off. Right: Water droplet on a regular leaf. The droplets are wetting the surface and sticking to the leaf.

13 Superhydrophobic and superhydrophilic surfaces with nanostructures A. Superhydrophilic surface on nanostructured silicon. This type of surfaces can be used for antifogging. B. Hydrophilic surface on a smooth silicon surface. C. Hydrophobic surface on a smooth silicon suface with teflon coating. D. Superhydrophobic surface on nanostructured silicon in combination with a hydrophobic coating. This type of surfaces are selfcleaning. Nanostructured surfaces can be designed for both hydrophilic and hydrophobic surfaces.

14 Anti-stiction surfaces, applications Up to 10% of the yogurt is normally left in the container due to stiction. This can be avoided with a nanostructured anti-stiction surface. The nanostructures are cast in the existing plastic container and no extra coating is needed.

15 The Honey Spoon The Honey Spoon without Nano surface. The Honey sticks til the surface The Honey Spoon with Nano surface. Notice that the Honey are released from the surface
