This article focuses on the effects of incomplete interfacial adhesion on the yield strength and interface/interphase properties of montmorillonite (MMT)/polymer nanocomposites (MPN). The minimum length of platelets necessary for efficient stress transfer from matrix to MMT (L-C) and the interfacial shear strength (tau) change the effective inverse aspect ratio (alpha = thickness/length) and the effective volume fraction of MMT in nanocomposites. These effective parameters are applied to express the yield strength and interface/interphase properties in MPN. It was found that large platelets, small L-C and high tau increased the yield strength of MPN and the high levels of L-C and alpha caused poor interface/interphase properties.
