Studies on the Gradient Phase Morphology of Polymer Blends Caused by Temperature Gardient

Abstract

Abstract: The gradient phase morphology of polymer blends caused by temperature gradient during quiescent annealing process was studied. The influence of volume fraction of dispersed phase and interfacial tension on the gradient phase morphology was discussed. The coarsening behavior of dispersed phase under temperature gradient was computed by the touch-coalescence mechanism. The results show that the degree of gradient phase morphology increases with interfacial tension and volume fraction of dispersed phase.
