Star polymers: From conformations to interactions to phase diagrams
We review recent progress achieved in the theoretical description of the interactions, correlations, and phase behavior of concentrated solutions of star polymers, sterically stabilized colloids, and micelles. We show that the theoretical prediction of an ultrasoft, logarithmically diverging effe...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We review recent progress achieved in the theoretical description of the
interactions, correlations, and phase behavior of concentrated solutions of
star polymers, sterically stabilized colloids, and micelles. We show that the
theoretical prediction of an ultrasoft, logarithmically diverging effective interaction
between the star centers, which has been confirmed by SANSexperiments
and computer simulations, lies in the core of a host of unusual
phenomena encountered in such systems. These include anomalous structure
factors, reentrant melting behavior, as well as a variety of exotic crystal
phases. Extensions to polydisperse stars and the role of many-body forces
are also discussed. A particular ‘mean-field’ character of star polymer fluids
is presented and it is shown that it manifests itself in the shape and
structure of sedimentation profiles of these systems. |
