ADHESION AT THE POLYMER MIXTURE SOLID INTERFACE

Thermodynamic approach to the adhesion of immiscible polymer blends is proposed based on the concept of selectivity of interaction of blend components with the surface Thermodynamic work of adhesion may be expressed as a sum of two terms characterizing thermodynamic. work of cohesion of two phases of varying composition formed at the interlace with solid. Mechanical model of Takayanagi type is proposed to describe the adhesion strength and conditions of failure of adhesion joints at the interface with solid.
