Abstract

The interface shear properties of thin bisphenol-A-poly(carbonate) films are measured and interpreted in terms of the effects of the morphology induced by solvent plasticisation. The variations in the interface rheology are discussed in terms of the Eyring stress modified thermally activated flow model. The changes in the molecular architecture, induced by plasticisation, are also examined using vibrational spectroscopy. A correlation is made between the proposed mechanism for microshear and the conveyed morphological properties of the polymer film at the molecular level.
