With 16 chapters from world-renowned researchers, this book offers an extraordinary commentary on the burgeoning current research activity in contact angle and wettability The present volume constitutes Volume 3 in the ongoing series Advances in Contact Angle, Wettability and Adhesion which was conceived with the intent to provide periodic updates on the research activity and salient developments in the fascinating arena of contact angle, wettability and adhesion. The book is divided into four parts: Part 1: Contact Angle Measurement and Analysis; Part 2: Wettability Behavior; Part 3: Superhydrophobic Surfaces; Part 4: Wettability, Surface Free Energy and Adhesion. The topics covered include: procedure to measure and analyse contact angle/drop shape behaviors; contact angle measurement considering spreading, evaporation and reactive substrate; measurement of contact angle of a liquid on a substrate of the same liquid; evolution of axisymmetric droplet shape parameters; interfacial modulus of a solid surface; functionalization of textiles using UV-based techniques for surface modification--patterned wetting behavior; wettability behavior of oleophilic and oleophobic nanorough surfaces; wettability behavior of nanofluids; dielectrowetting for digital microfluidics; hydrophobicity and superhydrophobicity in fouling prevention; superhydrophobic/superhydrophilic hybrid surface; determination of the surface free energy of solid surfaces: statistical considerations; determination of apparent surface free energy using hysteresis approach; wettability correlations for bioadhesion to different materials; laser material processing for enhancing stem cell adhesion and growth.

On the liquid 's surface, the molecules have fewer neighbors in comparison with the bulk volume. As a result, the energy interaction shows itself in the surface tension. Traditionally, the surface tension can be assumed as a force in the unit of the length which can be counted by the unit of Newton on squared meter, or energy on the units of the surface. The surface tension, implies the interface between liquid and vapor, which is an example of the surface tensions. The equilibrium between these surface tensions, decides that a droplet on a solid surface, would have a droplet form or will change to layer form. This book collects new developments in wetting and wettability science.

Superhydrophobic surfaces (water contact angles higher than 150a ) can only be achieved by a combination of hydrophobicity (low surface energy materials) with appropriate surface texture. In nature one can find an array of impressive and elegant examples of superhydrophobic surfaces. For example, on a lotus leaf rain drops bounce off after impact,

Superhydrophilic and superhydrophobic surfaces have potential for implementation into a variety of fields, including self-cleaning surfaces, anti-fogging transparent materials, and biomedical applications. In this study, sandblasting, oxygen plasma treatments, silica nanoparticle films, and a low surface energy fluorocarbon film were employed to change the natural surface wettability of titanium, glass, and polyethylene terephthalate (PET) substrates, with an aim to produce superhydrophilic and superhydrophobic behavior. The effects of these surface modifications are characterized by water contact angles (WCAs), surface wetting stability, surface morphology and roughness, surface elemental composition, and optical transmittance measurements. The results show that stable superhydrophilic and superhydrophobic surfaces can be fabricated on titanium; stable superhydrophilic and unstable nearly superhydrophobic surfaces can be fabricated on glass; and very hydrophilic (WCA ~ 10°) and very hydrophobic (WCA ~ 135°) surfaces can be produced on PET. In addition, the silica nanoparticle films utilized have antireflective properties and increase optical transmittance of glass and PET substrates across the entire visible spectrum. This thesis provides a foundation for further studies into the implementation of these functional surfaces into practical applications, as well as a deeper understanding of how the properties (morphology, roughness, chemistry, etc.) of these modified surfaces influence their surface wetting properties.
