New Material Coating Technology Mimics Nature’s Lotus Effect

Numerous methods currently exist to produce coating surfaces that for all practical purposes do not get wet as the water droplets run off the material. A few examples are: spraying; self-assembly where molecules spontaneously organize themselves into a structure; and laser etching.

But Ranga Pitchumani and Atieh Haghdoost explained their method “differs in that their two-step process is used to directly make superhydrophobic copper coatings without the more costly need for an additional layer of a low surface energy material.”
