Super Water-Repellant Coatings Can Now Take the Pressure

Posted On: 2015-09-01

"Conventional superhydrophobic coatings that repel liquids by trapping air inside microscopic surface pockets tend to lose their properties when liquids are forced into those pockets. In this work, extremely water-repellant or superhydrophobic surfaces were fabricated that can withstand pressures that are 10 times greater than the average pressure a surface would experience resting in a room. The surfaces resist the infiltration of liquid into the nanoscale pockets..."
