WebLet us begin with a brief review on the scaling theory for weak adsorption of a long flexible polymer with a segmental number N(N@1) onto a planar surface @3,6,11#. The persis-tence length l is now the Kuhn’s segmental length. The free energy F of adsorption is F5E2T~Sb1Sj!. ~1! The first term is the attraction energy acquired by adsorption ... Webics simulations. The simulations show how the scaling properties in these systems emerge and how the isotherms rescale to a universal curve, repro-ducing reported experimental results. The critical exponent for these systems is also obtained, in perfect agreement with the scaling theory of deGennes. Some important applications are mentioned.
Adsorption scaling theory for investigation of distance between …
WebJul 15, 2024 · The adsorption and wetting behaviors of polymer solutions in the presence of a solid surface are critical to the fabrication process of PNCs. In this study, we use both classical density functional theory (cDFT) and molecular dynamics (MD) simulations to study dilute and semi-dilute solutions of short polymer chains near a solid surface. WebScaling theory of polymer adsorption. P.G. De Gennes. Collège de France, 75231 Paris Cedex 05, France. Abstract. We discuss the equilibrium properties of flexible chains adsorbed … the gigls.com
Evaluating the dependency of polymer/particle interphase
WebJul 8, 2024 · The polymer/particle interphase regions are formed based on the adsorption of the polymer molecules onto the surface of the nanoparticles [ 12, 13, 18 ]. This can be ascribed to the mutual interaction between the chemical sites on the surface of the nanoparticles with specific groups of the polymer chains [ 12, 17 ]. WebMay 30, 1998 · Within a simple scaling model for the behavior of the loops and tails, we are able to relate the features of the interface to the “loop density profile” S̃(n), defined as the number of loops and tail having more than nmonomers on the particle.
