Hydrophilic materials can be made superrepellent to water by chemical texturing, a stochastic rather than deterministic process. Here, multiscale features render copper surfaces comparable to lotus leaves, in terms of wettability, texture and water repellency. The novel ability to make hydrophilic materials superrepellent without deterministic structuring opens the way to large-scale manufacturing of superrepellent surfaces.
