Abstract

This disclosure describes single and multi-layer woven meshes designed to enable sucking flow condensation and capillary-driven liquid film boiling, respectively, for instance, in use in heat spreaders. The single-layer woven meshes can include a nanostructure coating and a hydrophobic coating, while the multi-layer meshes can include a microcavity coating and optionally a hydrophilic coating.
