SUPERWETTING SURFACES FOR DIMINISHING LEIDENFROST EFFECT, METHODS OF MAKING AND DEVICES INCORPORATING THE SAME

摘要

Textured surface for increasing Leidenfrost temperature. The texture comprises of surface features over multiple length scales - from micro to nanoscaie - wherein the features at each length scale have a size, aspect ratio, and spacing selected to increase the Leidenfrost temperature. The structure includes an array of microscaie structures disposed on the surface, the structure having size, aspect ratio and spacing selected to increase Leidenfrost temperature. The microscaie structures may also include nanoscaie structures on their surface to create a hierarchical structure. The structures result in an increased Leidenfrost temperature.
