Title	A Theory of Polymer Adsorption from Solution
Author	Woongki Lee, Hyungsuk Pak*
Keywords
Abstract	A statistical thermodynamical treatment for polymer adsorption from solution is presented. The canonical partition function for the polymer solution in the presence of a surface or an impermeable interface is formulated on the basis of usual quasi-crystalline lattice model, Bragg-Williams approximation of random mixing, and Pak's simple treatment of liquid. The present theory gives the surface excess Γexc and the surface coverage øs2 of the polymer as a function of the chain length x, the Flory-Huggins parameter χ, the adsorption energy parameter χs, and polymer concentration v2. Present theory is also applicable to the calculation of interfacial tension of polymer solution against water. For the idealized flexible polymer, interfacial tensions according to our theory fit good to the experimental data to the agreeable degrees.
