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

Comprehensive resource covering the latest development of surface engineering inspired by nature with a special focus on wetting control Drawing from the natural abilities of plants and animals around the world, Controlled Surface Wetting takes a deep dive into wetting-controlled systems of biological surfaces with information on mechanisms, theory, surface design, fabrication, and effects. This book guides readers to design better engineering surfaces for applications in self-cleaning, water harvesting and repellency, anti-icing, liquid-transport, and beyond. Exploring the latest literature, this book introduces bioinspired techniques and methods to design wetting-controlled surfaces by using organic or inorganic materials, including those with high/low surface energy, regular/irregular, ordered/disordered, or rough/smooth surfaces, or endless arrangements and combinations of micro- and nanostructures of various styles. This book begins by introducing biological surfaces such as plant leaves and duck feathers, butterfly wings, and spider silks, as well as their functions, including superhydrophobic properties, water repellency, and capturing tiny water droplets, respectively, progressing through to more advanced topics such as dually-mobile super-repellency, multi-liquid repellency, and switchable repellency in both air and liquid. Controlled Surface Wetting includes discussion on: Fundamental wetting theories, extension and theoretical models, wetting dynamics and kinetics, physics of wetting, wetting adhesion, and wetting chemistryStatic and dynamic gradients, texture gradients such as gradient polymers, wedge- and helical-induced gradients, and synergism of multi-gradientsFormation, control, and instability of Rayleigh instability, microfluidics, fluid-coating, electrospinning, fluid diffusion, and laser techniquesCoalesced-droplet vertical transport, the hierarchical droplet size-effect, atmospheric water harvesting, and energy harvestingArtificial skins and sensors, including artificial skin vision, and medical applications, including directional-controllable drug deliveryControlled Surface Wetting is an up-to-date and completely comprehensive resource for students and researchers in chemistry, physics, and materials science seeking to learn about the design of smart and advanced materials for engineering applications.
