Abstract: Solid-infused surfaces and articles having solid-infused surfaces are provided. The solid-infused surface includes (a) a substrate with a roughened surface having multi-scale surface roughness and a plurality of substrate asperities, and (b) a low surface-energy polymer coating a portion of the roughened surface forming the solid-infused surface having a fraction of the substrate asperities exposed on the solid-infused surface. The surfaces can be useful, in particular, for promoting condensation heat transfer performance. The articles and surfaces can include electronic components, optical components, or even pipes and other conduits for transporting certain fluids. Methods of making and methods of using the solid-infused surfaces are also provided.
