Superhydrophobic surfaces with the self-cleaning behavior of lotus leaves are sought for drag reduction and phase change heat transfer applications. These superrepellent surfaces have traditionally been fabricated by random or deterministic texturing of a hydrophobic material. Recently, superrepellent surfaces have also been made from hydrophilic materials, by deterministic texturing using photolithography, without low-surface energy coating. Here, we show that hydrophilic materials can also be…

Dropwise Condensation on Multi-scale Bioinspired Metallic Surfaces with Nano-Features.

Continuous dropwise condensation on a hierarchical bioinspired lotus leaf metallic surface without the need for a conformal hydrophobic coating is demonstrated, which offers a novel path for the design and manufacture of non-coated metallic super-repellent surfaces for condensation phase change applications, amongst others.

This work reports on the facile strategy to prepare a new hierarchical multilayered superhydrophobic surface directly from commercially available porous matrix that allows for efficient drop shedding and shows that the enhanced drop mobility observed on such a surface is attributed to the synergistic cooperation of hierarchical structures.

Wetting characteristics of Colocasia esculenta (Taro) leaf and a bioinspired surface thereof

It is found that the measured static contact angle on the bioinspired surface varies with b/a and this variation is consistent with a free-energy based model for a droplet in Cassie-Baxter state, and the measured angles in full Wenzel state are closer to the predictions of the free- energy based model.
