摘要: Numerical simulation based on the modified time-dependent Ginzburg–Landau (TDGL) model has been performed domain growth and related rheological properties of binary mixtures under oscillatory shear. The results reveal that is anisotropic depends quench depth. It found that, in deep case, disclike with normal parallel to velocity gradient direction observed, while shallow rodlike rod axis aligned along flow observed. scattering functions for different light incident directions are calculated suggest undulated morphology formed case. This shows anomalous response. A plausible interpretation property proposed deformation
