Adhesion of Polymer Blends. I. Phenomenological Model

Abstract A phenomenological model based on the Takayanagi approach is proposed to describe the adhesion of polymer blends to a solid support. The model consists of three elements corresponding to two components of the blend and a solid surface. The conditions for failure of the adhesion joints at the interface between the solid surface and the polymer blend are found to depend on the blend composition and the moduli and adhesion joint strength of each component to the solid.
