The book will begin with descriptions of the nature of colloids, interfaces, surfactants and solution polymers. Chapters 2 and 3 will introduce macromolecules and surfactants and interactions between colloidal particles, respectively. Chapter 4 will focus on the forces of repulsion including electrostatic interactions and Chapter 5 will review the stability of dispersions. The wetting of surfaces by liquids will be discussed in Chapter 6 and Chapter 7 will present information on emulsions and microemulsions including emulsification and the stability of emulsions. Chapter 8 will describe the various characterization methods of colloidal particles such as microscopy and scattering methods. The final chapter will be on concentrated dispersions. There will be new material on fluorescence microscopy, sedimentation and strategies for the control of sedimentation, phenomenology, biopolymers and new nanoparticles as well as a section on polyelectrolytes.
