The Challenge

Zoom into a lotus leaf, a butterfly’s wing, or a moth’s eye and you’ll see intricate arrays of extremely tiny bumps, precisely positioned to repel water, dirt, or bacteria––or even to provide color or to better absorb light––without the organism having to expend any additional energy. Humans often achieve these qualities through the use of toxic chemicals or large amounts of water or other resources. Laser etching and other machining techniques have allowed humans to create similar nano textures that impart function directly onto surfaces, but they are slow and energy-intensive, and difficult to use at scale.

Innovation Details

Scientists at Fusion Bionic have found an extremely efficient way of nano-texturing surfaces by harnessing the properties of light itself. Instead of using a laser beam like a knife to etch a surface line by line, they control the interference pattern of multiple sub-beams to use like a stamp to produce a complete texture all at once. They call this “Direct Laser Interference Patterning (DLIP)”. This technique can efficiently produce functional textures, mimicking nature’s surfaces, and replace costly traditional methods of finishing surfaces.

In DLIP, laser beams are combined in a controlled manner to create a defined interference pattern within the processing area. The pattern produced is much smaller than the laser beam itself with typical resolutions in the range of 300 nm up to 30 μm. Due to the interference effect, areas of high intensity (interference maxima) and zero intensity (interference minimums) are present within the laser beam. During machining, the material surface is only modified at the intensity maximums, the remaining areas remain unaffected.

The patterns created with Fusion Bionic’s DLIP technology can be transferred to almost all materials, from metals and polymers to ceramics, coatings, and glass.

Biological Model

Zoom into a lotus leaf, a butterfly’s wing, or a moth’s eye and you’ll see intricate arrays of extremely tiny bumps—precisely positioned to repel water, dirt, or bacteria—or even to better absorb light––without the organism having to expend any additional energy.

Lotus leaves are covered with rows and rows of nanoscale pillars—each about 400 times thinner than a strand of human hair. Water landing on these bumpy surfaces has no flat surface to stick to. Instead, the molecules stick to one another, forming droplets that slide off, flushing along dirt particles and contaminants with them.

Other organisms use similar texturing for the opposite effect: When light hits the eyes of moths, it doesn’t bounce off the intricate nanopillared surfaces at all. Instead, the waves get trapped and absorbed in the gradually narrowing spaces between nanopillars, creating a naturally anti-reflective surface.
