Neutral and Charged Polymers at Interfaces *
Chain-like macromolecules (polymers) show characteristic adsorption properties due to their flexibility and internal degrees of freedom, when attracted to surfaces and interfaces. In this review we discuss concepts and features that are relevant to the adsorption of neutral and charged polymers at equilibrium, including the type of polymer/surface interaction, the solvent quality, the character...
متن کاملStatistical thermodynamics of equilibrium polymers at interfaces.
The behavior of a solution of equilibrium polymers (or living polymers) at an interface is studied, using a Bethe-Guggenheim lattice model for molecules with orientation dependent interactions. The density profile of polymers and the chain length distribution are calculated. For equilibrium polymers at a nonadsorbing surface it is found that the depletion layer thickness has a maximum. In dilut...
متن کاملEnhanced structure in polymers at interfaces
We explore the conformations of an isolated chain molecule as it approaches an impenetrable planar surface, by exhaustive enumeration of all the three-dimensional self-avoiding flights on simple cubic lattices. We confirm the well-known results that as a chain approaches a surface, the number of accessible configurations diminishes, so there is an entropic repulsion, and the radius of gyration ...
متن کاملPolymers at interfaces and surfaces and in confined geometries
Inhomogeneous polymer systems have attracted abiding technological interest (Advincula et al., 2004; Cahn et al., 1993; Garbassi et al., 2000; Granick et al., 2003a; Karim and Kumar, 2000; Stamm, 2008). The surface of a polymer liquid determines the wetting properties, adhesion, corrosion, and friction as well as the gloss of a polymeric material. Polymers do not only find application in form o...
متن کاملThermodynamics of linear and star polymers at fluid interfaces.
Performing molecular dynamics simulations on model systems we study the structural changes and thermodynamic stability of polymers of varying topology (linear and star-shaped) at interface between two liquids. We find that homopolymers are attracted to the interface in both good and poor solvent conditions showing that they are surface active molecules even though not amphiphilic. In most cases...
