Lotus effect shakes off dirt
The lotus - a flowering wetland plant native to Asia - may not, at first glance, be of interest to you. But researchers at MacBRITE now developped a car wax that mimics the way lotus leaves repel water droplets and particles of dirt.
Lotus plants have superhydrophobic surfaces: water droplets falling onto them bead up and, if the surface slopes slightly, will roll off. As a result, the surfaces stay dry even during a heavy shower. What's more, the droplets pick up small particles of dirt as they roll, so that the lotus leaves are self-cleaning.
MacBRITE's lotus autopolish combines nanoparticles with hydrophobic polymers such as polypropylene, polyethylene micro waxes and fruit oils. As it dries, the coating develops a lotosstructure through self-assembly. The self-cleaning surface may soon be a reality.
