Mean Field Theory Study on the Wetting Transitions of Polymer Solutions
The interfacial properties of polymers in poor solvent near a single solid surface were systematically studied by using the self-consistent mean field theory.The effects of chain length N,interaction between surface and polymer monomerεs,solvent quality x,and polymer concentration φb on the density distribution along the direction z perpendicular to the substrate φ(z)and the adsorption amount Γ were analyzed.The transition point of wetting and drying as well as the transition order were determined respectively,and it was found that in most cases,the transitions are of the first-order.This study provides new understandings on the interfacial properties of polymer solutions.
