abstract = {The petal effect is identified as a non-wetting state with high drop adhesion. The wetting behavior of petal
surfaces is attributed to the papillose structure of their epidermis, which leads to a Cassie-Baxter regime combined
with strong pinning sites. Under this scenario, sessile drops are pearl shaped and, unlike lotus-like surfaces,
firmly attached to the surface. Petal surfaces are used as inspiration for the fabrication of functional parahydrophobic
surfaces such as antibacterial or water-harvesting surfaces. In this work, two types of rose petals
were replicated by using a templating technique based in Polydimethylsiloxane (PDMS) nanocasting. The
topographic structure, the condensation mechanism under saturated environments and the wetting properties of
the natural rose petal and their negative and positive replicas were analyzed. Finally, we performed prospective
ice adhesion studies to elucidate whether petal-like surfaces may be used as deicing solutions.},
