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.

Intelligent materials are emerging composite functional materials that have boomed since the 1990s. The intelligent material system, involving a multitude of structures and functions, combines studies that explore nature, mimic nature and surpass nature. It also provides novel ideas, new theories, and cutting-edge methodologies for the innovation of science and technology. Thus, mimicking the micro/nanostructures and functions found in nature will build a bridge between biology and technology, which may provide inspirations for solving today's technological problems. This book gives a complementary introduction about natural and artificial micro/nanoscale interfacial materials, devoting largely to the intelligent materials with special wettabilities. Inspired by nature, the authors proposed a concept of "binary cooperative complementary micro/nanoscale interfacial materials". Based on this design concept, the contact and coupling of heterogeneous materials will result in novel properties on the surface or interface of materials, which may create new functional materials and devices. This book combines popular science and professional knowledge, which will be suitable for not only researchers but also science lovers.

This book is the second volume in the series "Contact Angle, Wettability and Adhesion." The premier volume was published in 2013. Even a cursory glance at the literature show that in recent years the interest in understanding and controlling wetting behavior has grown exponentially. Currently, there is tremendous research activity in rendering surfaces superhydrophobic, superhydrophilic, superoleophobic, superoleophilic, omniphobic and omniphilic because of their applications in many technologically important fields. Also the durability or robustness of materials with such super" characteristics is extremely significant, as well as the utilization of "green" (biobased) materials to obtain such surfaces. This book containing 19 articles reflects more recent developments in certain areas covered in its predecessor volume as well as it includes some topics which were not covered before. Concomitantly, this book provides a medium to keep abreast of the latest research activity and developments in the arena of contact angle, wettability and adhesion. The topics discussed include: Understanding of wetting hysteresis; fabrication of superhydrophobic materials; plasma treatment to achieve superhydrophilic surfaces; highly liquid repellent textiles; modification of paper surfaces to control liquid wetting and adhesion; Cheerios effect and its control; engineering materials with superwettability; laser ablation to create micro/nano-patterned surfaces; liquid repellent amorphous carbon nanoparticle networks; mechanical durability of liquid repellent surfaces; wetting of solid walls and spontaneous capillary flow; relationship between roughness and oleophilicity; superhydrophobic and superoleophobic green materials; computational analysis of wetting on hydrophobic surfaces: application to self-cleaning mechanisms; bubble adhesion to superhydrophilic surfaces; surface free energy of superhydrophobic materials; and role of surface free energy in pharmaceutical tablet tensile strength.

Materials with superhydrophobic or related properties are one of the most studied subjects from a theoretical point of view and also for the large range of possible applications, for example, anticorrosion, antibacteria, optical devices, and sensors. The study of natural species with special wettability has shown us the importance of surface structures and the surface energy of the resulting surface properties. Various strategies can be used to reproduce superhydrophobic phenomena in the laboratory. General reviews on superhydrophobic properties already exist but, to our knowledge, do not focus on metallic and inorganic materials. Here, we focus especially on the strategies implemented for reaching superhydrophobic or related properties using metallic and inorganic materials. Indeed, these materials present unique properties, for example, thermal and mechanical resistance, chemical and ageing resistance, and optical (transparency, antireflection, photoluminescence) and electrical properties (conducting, semiconducting, insulating). This book will be useful for graduate students of materials chemistry and physics and for researchers in surface science, nanostructures, and bioinspired or biomimetic materials.
