Adsorption of Polymers on a Fluctuating Surface
نویسندگان
چکیده
We study the adsorption of polymer chains on a fluctuating surface. Physical examples are provided by polymer adsorption at the rough interface between two non-miscible liquids, or on a membrane. In a mean-field approach, we find that the self–avoiding chains undergo an adsorption transition, accompanied by a stiffening of the fluctuating surface. In particular, adsorption of polymers on a membrane induces a surface tension and leads to a strong suppression ∗Permanent address: Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA †Permanent address: Service de Physique Théorique, CE-Saclay and Groupe de Physique Statistique, Université de Cergy-Pontoise, 95806 Cergy-Pontoise Cedex, France 1 of roughness.

Adsorption of comb copolymers on weakly attractive solid surfaces.
In this work continuum and lattice Monte Carlo simulation methods are used to study the adsorption of linear and comb polymers on flat surfaces. Selected polymer segments, located at the tips of the side chains in comb polymers or equally spaced along the linear polymers, are attracted to each other and to the surface via square-well potentials. The rest of the polymer segments are modeled as t...
متن کاملA short review on Ferrofluids surface modification by natural and biocompatible polymers
This paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. Among common magnetic nanoparticles, magnetite (Fe3O4) and maghemite (g-Fe203) are popular candidates because of their biocompatibility. Natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...
متن کاملEvidence of random copolymer adsorption at fluctuating selective interfaces from Monte-Carlo simulation studies.
We perform Monte-Carlo simulations of a binary, strongly separated mixture of A- and B-type homopolymers with some amount of random AB copolymers added. The interface is analyzed and the interface tension is calculated using the model of capillary waves. We can clearly demonstrate that random copolymers are localized at real, fluctuating interfaces between incompatible polymer species and micel...
