Late stages of spinodal decomposition

Now, we turn our attention to late stages of spinodal decomposition. Since the phase separation in binary mixture is intrinsically a nonlinear phenomenon, a number of nonlinear theories have been put forward on the basis of statistical consideration, notably the LBM (Danger, Baron k Miller) (H) and BS (Binder k Stauffer) (12) theories. Both theories predicted the power law scheme rather than the exponential growth of the structure...

Fig. 3.35. Structure development during the late stages of spinodal decomposition observed for a PS/PBrxS-(l l) mixture. Micrographs were obtained during annealing at 200°C (< Tc = 220°C) for 1 min (left), 3 min (center) and 10 min (right) [17]...

Fig. 3.36. Light scattering curves obtained for a PB (M = 5.8 10 )/PIP (M = mixture during the late stage of spinodal decomposition at the indicated temperatures top] curves for 45 °C and 60 °C are shifted by constant amounts in vertical direction). Each curve contains measurements for different times and these superpose exactly. Time dependence of the interfacial area per unit volume, O12, in agreement with a power law O12 t, as indicated by the straight line with slope -1 bottom). Data from Takenaka and Hashimoto [24]...
