Bio Inspired Wettability Surfaces

Through natural evolvement in thousands of years, biosurfaces have become highly adaptable to display their biological functions perfectly. Interestingly, they have developed micro-/nanostructures with gradient features to achieve smart wetting controls, such as ultra-hydrophobic water repellency in lotus leaf, directional water collection in wetted spider silk, directional adhesion in superhydrophobic butterfly wing, and fog-collecting hydrophobic/hydrophilic pattern on beetle back. These surfaces provide endless inspiration for the design and fabrication of functional interface materials with unique wettability, generating promising applications such as micro-fluidic devices, functional textiles, corrosion resistance, liquid transportation, antifogging, and water-collecting devices. In recent years there has been an exciting confluence of research areas of physics, chemistry, biology, and materials science to develop functional micro- and nanosurfaces. A kernel consists of organic materials with high/low surface energy and regular/irregular order/disorder, which can be rough/smooth and endlessly arranged and combined with various styles of micro- and nanostructures. This book introduces recent research on wettability of biological and bio-inspired surfaces. It discusses the mechanism of smart wetting controls, such as water collection/repellency on biological micro-/nanostructure gradient interfaces. It suggests ways to mimic these biological features to realize bio-inspired functional surfaces with unique wettability. The book will help researchers innovate designs with novel materials for future scientific works.

Bioinspired Design of Materials Surfaces reviews novel methods and technologies used to design surfaces and materials for smart material and device applications. The author discusses how materials wettability can be impacted by the fabrication of micro- and nanostructures, anisotropic structures, gradient structures, and heterogeneous patterned structures on the surfaces of materials. The design of these structures was inspired by nature, including lotus, cactus, beetle back and butterfly wings, spider silk, and shells. The author reviews the various wettability functions that can result from these designs, such as self-cleaning, directional adhesion, droplet driving, anti-adhesion, non-wetting, liquid repellent properties, liquid separation, liquid splitting, and more. This book presents a key reference on how to fabricate bioinspired structures on materials for desired functions of materials wettability. It also discusses challenges, opportunities and many potential applications, such as oil-water separation devices, water harvesting devices and photonic device applications. Introduces the fundamentals of both bioinspired materials design and the theory behind dynamic materials wettability Reviews the latest methods and technologies used to create functional surfaces and structured materials that impact and potentially control wettability Provides a snapshot of potential device applications, such as oil-water separation, water harvesting, fluid transport, photonic applications, and much more

Through millions of years' natural selection, sharkskin has developed into a kind of drag-reducing surface. This book shows how to investigate, model, fabricate and apply sharkskin's unique surface properties, creating a flexible platform for surface and materials engineers and scientists to readily adopt or adapt for their own bio-inspired materials. Rather than inundate the reader with too many examples of materials inspired by nature, sharkskin has been chosen as the center-piece to illustrate accurate 3D digital modeling of surfaces, complete numerical simulation of micro flow field, different fabrication methods, and application to natural gas pipelining. This is a must-read for any researcher or engineer involved in bio-inspired surfaces and materials studies.

Superhydrophobic surfaces, artificially mimicking lotus leaves, have captured the attention of scientists and engineers over the past few decades. Recent trends have shifted from superhydrophobicity to superominipohobicity, or superamphiphobicity. In addition, dynamic rather than static surface wetting/dewetting properties, which can be triggered by various stimuli, including temperature, pH, magnetic/electric fields, solvents, light exposure etc, have been highly sought after for commercial applications. This book will focus on recent topics related to various stimuli-responsive wetting/dewetting surfaces, and give an overview of the knowledge and concepts of how to design and establish these smart artificial surfaces, which can be used for technical developments in a wide variety research fields.
