Adopting an integrated approach, this book covers experiments, theory, and emerging applications. It addresses a number of materials and includes a discussion of various applications.

Adopting an integrated approach, this book covers experiments, theory, and emerging applications.
In the first part surfaces are described that change from flat to either a random corrugated or to a well-structured structure, while the second part deals with those surface structures integrated in the coating surface where the structures change their shape or dimension when addressed by an external trigger. A variety of materials are addressed, including liquid crystal polymers, hydrogels, hard acrylates, and soft silicones. The whole is rounded off by a discussion of various applications, including surface controlled flows in microfluidic systems.
Of interest to chemists and engineers, researchers in industry and academia, as well as those working in the paint industry and hydrodynamics.
