Summary:

This book explores the state of the art concerning the development and use of micro/nanotechnologies for the design of synthetic liquid-repellent surfaces with a particular focus on super-oleophobic materials. It proposes a comprehensive understanding of the physical mechanisms involved in the wetting of these surfaces and reviews emerging applications in various fields such as energy harvesting and biology, as well as highlighting the current limitations and challenges which are yet to be overcome. As such, this book is particularly suited to researchers, engineers and students interested in micro- and nanotechnologies dedicated to wetting phenomena (repellency, drag reduction biofouling, lab-on-a-chip, displays, self-assembly, biosensing, biology, petrol extraction, and so on.)
