Biomimetics inspired surfaces: for superhydrophobicity/self-cleaning, and controlled adhesion

This book presents an overview of the general field of biomimetics - lessons from nature. It presents various examples of biomimetics, including roughness-induced superomniphobic surfaces which provide functionality of commercial interest. The major focus in the book is on lotus effect, rose petal effect, shark skin effect, and gecko adhesion. For each example, the book first presents characterization of an object to understand how a natural object provides functionality, followed by modeling and then fabrication of structures in the lab using nature’s route to verify one’s understanding of nature and provide guidance for development of optimum structures. Once it is understood how nature does it, examples of fabrication of optimum structures using smart materials andfabrication techniques, are presented. Examples of nature inspired objects are also presented throughout. Presents the field of biomimetics didactically. Displays the commercial interest in applying biomimetics. Discusses in detail the important effects: lotus effect, shark skin effect, rose petal effect. Explains learning from naturefor technology INDICE: Preface. Introduction.
