Biomimetics studies of Salvinia molesta for fabrication

It has been reported that the sophisticated structure of the Salvinia molesta surface offered a novel mechanism for long‐term air‐retention. It was difficult to mimic the structure, for it was composed of complex elastic eggbeater‐shaped hairs with a coating of nanoscopic hydrophobic wax crystals, except for the top of the hairs. In this work, a structure of fibres cross on a patterned paper to mimic the ability of S. Molesta is manufactured. The complex elastic eggbeater‐shaped hairs with a coating of SU‐8 photoresist can support a droplet water of 1 ml. This work offered a new simple method to mimic the properties of S. molesta surface.
