Title: Scaling properties of the morphological measures at the early and intermediate stages of the spinodal decomposition in homopolymer blends
Abstract: The spinodal decomposition of the homopolymer blends has been studied by numerical integration of the Cahn-Hilliard-Cook equation. We have the time evolution of the morphological measures that quantitatively the interface in the system. For symmetric we have found that the Euler characteristic of the interface is and increases with time as tau(0.75) (connectivity of the decreases) regardless of the final quench temperature. The index of the interface is constant in this case. This that at the level of the integral geometry quantities functionals), the dynamic scaling hypothesis holds for the of the interface morphology in quenched critical systems. The morphological evolution of the asymmetric blends have been Also, we have shown that the thermal fluctuations can modify the curvature distribution. (C) 2000 American Institute of Physics.
