Colloids and the Depletion Interaction
Colloids are
submicron
particles that are ubiquitous in nature (milk, clay, blood) and
industrial products (paints, drilling fluids, food). It has been known for a long time
that adding salt or polymer influences the characteristics of colloidal suspensions.
Think of the Egyptians who engineered ink by adding gum Arabic to soot particles a
few thousand years ago. Unknowingly, they were taking advantage of the anchoring of
the polysaccharides onto the colloids to provide the stabilization of the soot particles
that
eventuali)·
provided an ink to write on papyrus. The effect of charges and polymers
attached to the surface of colloidal particles on their
stabilit)·
has been understood and
studied extensively in the last century. But the more elusive, albeit ubiquitous, effects of
the addition of free polymers and small colloids as depletants to colloidal dispersions
have become in focus recently. In recent decades it has become clear that adding such
depletants allows one to tune the interactions between the colloids and in this way
control the stability, structure and rheological properties of colloidal dispersions. This
book offers a concise introduction to the fundamentals of depletion effects and their
influence on the phase behavior of colloidal dispersions. These fundamental principles
promote insight and the intuitive sense needed to isolate issues related to depletion
effects in technological problems and design critical experiments. In an introductory
chapter, the authors provide a historical perspective and the applications of depletion
effects not only in colloid science but also in biology, medicine and technology. In the
subsequent chapter they address the basics of depletion interactions, including the
effects of anisotropic depletants. The next chapter covers the basics of phase behavior
in colloidal dispersions, followed by extensions towards mixtures of spherical colloids
with polymers or small colloids inducing depletion forces. Finally, the authors consider
depletion effects in suspensions of rod-like colloids. Throughout the book, conceptual
explanations are accompanied by experimental and computer simulation results. This is
an ideal book tor advanced undergraduates and graduate students in physical chemistry,
chemical engineering and soft matter physics. It provides the basic knowledge ot
depletion interactions and phase behaviour in general. Experienced scientists and
engineers working on polymers, particles or colloidal dispersions, may also
ńnd
this
book useful. |
