Self Cleaning Surface Made By Laser

Using an ultra fast femtosecond laser on plastic surface, PhD student Max Groenendijk of the Applied Laser Technology Group of the University of Twente (Netherlands) got remarkable results.

The Lotus leaves present numerous tiny pillars with a wax layer on top, which keep water droplets away, mold them into a spherical shape, impeding them to cover the surface.

This way, dirt particles cannot stick to the surface through water. The researchers wanted to make a similar surface, but without using wax.

The light pulses are so short that they can be seen as light €˜bullets€™ with which the surface is bombed.
