Capillarity And Wetting Phenomena
Drops, Bubbles, Pearls, Waves
The study of capillarity is in the midst of a veritable explosion. What is offered here is not a comprehensive review of the latest research but rather a compendium of principles designed for the undergraduate student and for readers interested in the physics underlying these phenomena.

The study of capillarity is in the midst of a veritable explosion.Hence the temptation to write a new book, aiming at an audience ofstudents. What is offered here is not a comprehensive review of thelatest research but rather a compendium of principles.How does one turn a hydrophilic surface into one that is hydrophobic,and vice versa? We will describe a few solutions. Some rely onchemical treatments, such as coating a surface with a molecular layer.Others are based on physics, for instance by controlling the roughnessof a surface. We will also examine the dynamics of wetting. Drops thatspread spontaneously do so at a rate that slows down with time. Theycan be tricked into covering large areas by spreading them suddenly.We will describe a few of the many facets of their dynamicalproperties.Special additives are required for water to foam. Foams are desirablein a shampoo but can be a nightmare in a dishwasher detergent.Antifoam agents have been developed and are well known, but how dothey work? It is also possible to generate bubbles and foams withoutspecial additives, for example in pure and viscous liquids such asglycerin, molten glass, and polymers. As we will see, the laws ofdraining and bursting then turn out to be quite different from theconventional ones.This book will enable the reader to understand in simple terms suchquestions that affect every day life -- questions that also come upduring in industry. The aim is to view systems that often prove quitecomplex in a way that isolates a particular physical phenomenon, oftenavoiding descriptions requiring advanced numerical techniques willoftentimes in favor of qualitative arguments. This strategy may attimes jeopardize scientific rigor, but it makes it possible to graspthings efficiently and to invent novel situations.
