project investigates if it is possible to mimic the colour and mirror effects
found in nature and produce similar micro- and nanostructures artificially.
The hope is to produce coloured and reflective surfaces using the same principles
as nature and achieving benefits like new visual effects, new and brighter
colours, better reflections, more long lasting surfaces and better environmental
performance with respect to pollution and use of resources. The surfaces
should be complex free-formed and it should be possible to coat dielectric
materials with low melting points like polymers.
The resulting technology is intended to be used in a broad range of consumer
products as well as architectural elements. It would be a more environmentally
friendly alternative to pigment based paint and metallization. Furthermore
the new aesthetic possibilities will help industrial designers and architects
in creating attractive appearances in future products. This is important
in many industrial sectors, since aesthetics and product appearance is becoming
an increasingly significant position parameter. The project searches for
alternative coating principles, materials and microstructuring principles,
and experimentally try to produce coatings with the vivid colour effects
and metallic reflections seen in the beetle shells.
The project also examines the material innovation process by mapping the
progress and identifying key factors important for idea generation, phenomena
analysis, requirement understanding, solution generation as well as the
accept and propagation of the found solutions.
