内容説明
This volume chronicles the proceedings of the 5th International Symposium on Contact Angle, Wettability and Adhesion Toronto, Canada, June 2006.
Wettability is of pivotal importance in many and varied arenas, ranging from mundane to micro-and nanofluidics to lithography to biomedical. It should be underscored that in the last years there has been burgeoning interest in replicating the so-called "Lotus Leaf Effect" to create superhydrophobic surfaces.
This volume contains a total of 19 papers covering many facets of contact angle, wettability and adhesion. All manuscripts were rigorously peer-reviewed and revised and edited before inclusion in this book. Concomitantly, this volume represents an archival publication of the highest standard.
This book (5th volume in the series) is divided into three parts: Part 1: Contact Angle Measurements and Solid Surface Free Energy; Part 2: Relevance of Wetting in Cleaning and Adhesion; Part 3: Superhydrophobic Surfaces.
The topics covered include: Fundamental aspects of contact angle and its measurement; solidification contact angles of micro-droplets; microscopic wettability of wood call walls; dynamic vapor-liquid interfacial tension; surface free energy of polymeric materials; surface cleanliness evaluation from wettability measurements; wettability parameters affecting surface cleanability of stainless steel and textiles; wetting and adhesion in fibrous materials; wettability and adhesion of coatings; adhesion of hydrophobizing agents; modulation of surface properties of polymers; graft efficiency and adhesion; relevance of interfacial free energy in cell adhesion; various approaches to create superhydrophobic surfaces; adsorption of surfactants on hydrophobic and superhydrophobic surfaces.

内容説明
The topic of wettability (measured in terms of contact angle) is of tremendous interest from both fundamental and applied points of view, Wettability plays an essential role in many industrial processes, so an understanding of factors dictating wettability and how to modulate it is of paramount importance. In the last years there has been an explosive interest in superhydrophobic surfaces (i.e., surfaces with water contact angle of 150 Degrees or higher) because of their relevance/importance in many areas ranging from self-cleaning windows to nanofluidics. Also recently there has been heightened activity in the field of electrowetting.
This book is divided into four parts: Part 1: Fundamental Aspects; Part 2: Wettability Control/Modification; Part 3: Superhydrophobic Surfaces; and Part 4: Surface Free Energy and Relevance of Wettability in Adhesion. The topics covered include: a guide to the equilibrium contact angles maze: fundamental aspects of wetting of rough and chemically heterogeneous surfaces: work of adhesion for rock-oil-brine systems; Is the world basic?; wettability control/modification using various approaches; superhydrophobic surfaces and ways to impart superhydrophobicity; adsorption on superhydrophobic surfaces; solid surface energy determination; surface modification of different materials; relevance of wettability and adhesion aspects in a variety of reinforced composites.
In essence, this volume reflects the cumulative wisdom of many active and renowned researchers and provides a commentary on contemporary research in the fascinating world of contact angles and wettability. This volume and its predecessors (5 volumes), containing bountiful information, will be of much value to anyone interested/involved in controlling wetting phenomena and their applications.

内容説明
This volume documents the proceedings of the Second International Symposium on Contact Angle, Wettability and Adhesion held in Newark, NJ, June 21-23, 2000. Since the first symposium, held in 1992, there had been tremendous research activity on many ramifications of wettability phenomena.
This volume contains a total of 33 papers, which were all properly peer reviewed, revised and edited before inclusion. Therefore, this book is not merely a collection of unreviewed manuscripts, but rather represents information which has passed peer scrutiny. Furthermore, the authors were asked to update their manuscripts, so the information contained in this book should be current and fresh.
The book is divided into three parts: 1) General Papers; 2) Contact Angle Measurements / Determination and Solid Surface Free Energy; and 3) Wetting and Spreading: Fundamental and Applied Aspects. The topics covered include: various factors influencing contact angle measurements; various ways to measure contact angles; contact angle hysteresis; microscopic studies of static and dynamic contact angles; monitoring surface properties by contact angle measurements; contact angle measurements on various materials (smooth, rough, porous, heterogeneous); microtensiometry to determine contact angles on individual particles; surface free energy determination of various polymeric materials via contact angle measurements; factors influencing wetting and spreading phenomena; dewetting kinetics; wetting properties of wood, coal, paper, human skin and optoelectronic materials; droplet deposition on fibers; electrowetting; and relation between wettability and adhesion.
This volume represents a commentary on the current R&D activity in this arena and it should aEURO" together with its predecessor (Volume 1) aEURO" be of great value and interest to anyone interested in this topic.
