Imagine a coating that cause water to bead into almost perfect spheres , to enable any open to mimic the incredible water repellant properties of the lotus leaf . California - basedSeashell Technology , a National Science Foundation Small Business Innovation Research program grantee has build up a sprayable coating that does just that .
Researchers have developed spray coatings that mimic the extremely water-repellent properties of the lotus leaf.
The extreme water repellency is due , in part , to roughness at the nanoscale and microscale levels — which is created as the coating cures — as with a sacred lotus leaf , each water droplet sits on top of minuscule aerofoil bumps . Formulated to influence with a change of substrate , the companionship ’s Hydrobead coating provides weather resistance and anti - icing performance .
This form of superhydrophobic , or improbably water resistant , coating is characterise by quantifying the degree to which H2O will bead on a aerofoil . This is measured by place a drop of water on a Earth’s surface and measuring the slant between the surface and the edge of the water droplet . This angle is call the water contact angle .
For angles close to 0 degrees , the surface is considered hydrophilic ; as the contact slant increases to corking than 90 degree , the airfoil is conceive hydrophobic . For savourless , bland surfaces , the water inter-group communication angle maxes out at roughly 120 grade , which is distinctive for fluorinated aerofoil such as Teflon or other compounds .
Researchers have developed spray coatings that mimic the extremely water-repellent properties of the lotus leaf.
Compared to those coatings , the Hydrobead coating has a water system contact slant greater than 150 degrees .
Seashell Technology ’s coatings have also been characterise for anti - ice behavior — because of their special water repellant properties , they inhibit the buildup of ice crystals on surface . In general , the anti - ice belongings of the finishing can be determined by measuring the force required to take away chalk frozen on a surface .
