Interpretive Summary:

Technical Abstract: Interfacial tension is a critical parameter in determining and controlling the developed morphology in polymeric blends. Compatibilizers are often utilized to tailor the interfacial tension and, hence, develop specific morphologies, which will result in the desired final-state properties. This paper will discuss the application of a dynamic method to measure the interfacial tension of ternary blends of poly(methyl methacrylate) (PMMA), poly(vinylidene fluoride) (PvdF), and polcarbonate (PC). The method involves the microscopic tracking of the shape evolution of one fiber embedded in a matrix of a second material. The interfacial tension was found to be non-linear with respect to the PMMA/PvdF phase composition. The results are shown to be consistent with surface thermodynamic theories.
