Behavior of macromolecules in adsorbed layers

  • 38 Accesses

Abstract

A model for describing the behavior of macromolecules in adsorbed layers is developed by introducing a concept of distribution density of layer thicknessU based on stochastic process and probabilistic statistics. The molecular behavior of layers adsorbed on clay particle surfaces is discussed; the random distribution and its statistics of the layer thickness are given by incorporating experimental results with an ionic polyelectrolyte with the molecular weight of 1.08 x 106and chain charged density of 0.254.
