Thermodynamics of polymer solutions using simple theory
Aimee BaileyImperial College, London
The Flory-Huggins equation for the free energy of mixing of a polymer solution was revolutionary because, although many simplifying assumptions were made in its derivation, it was able to shed light on previously unexplained experimental results. The use and improvement of the theory is still an open area of research. Most gain their intuition of the equation from the textbook derivation; however, there are other ways of arriving at the Flory-Huggins result that provide a clearer insight into its meaning. We present alternate derivations which provide the clarity that is necessary for subsequent use and improvement of the theory.
