We review various simple analytical theories for homopolymers within a unified framework. The common guideline of our approach is the Flory theory, and its various avatars, with the attempt at being reasonably self-contained. We expect this review to be useful as an introduction to the topic at the graduate student level.

The electrosorption behaviour of non-ionic surfactant: N-decanoyl-N-methylglucamine on mercury electrode in 1 mol dm−3 NaClO4 solution was determined. The values of the relative surface excess were determined on the basis of double layer differential capacity. A set of parameters of maximal adsorption and the constants of Frumkin, modified Flory-Huggins and virial adsorption isotherms were obta...

A new theory model based on the local composition concept (TNRF-modified NRTL (TNRF-mNRTL) model) was developed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. An equation represented the activity coefficient of solvent was derived from the proposed excess Gibbs energy equation. The short-range contribution of interaction ...
