摘要: A survey is given on the effects of large amplitude oscillatory shear (LAOS) flow orientation behavior lamellar poly (styrene-b- isoprene) (PS-b-PI) diblock copolymers with emphasis elucidation common other layered complex fluids like lyotropic phases. It described that for LAOS at temperatures close to order-disorder-transition temperature, T ODT, three regimes related dynamic viscosity block are observed: parallel high, perpendicular intermediate, and again very low frequencies. demonstrated one key issues understand these non- equilibrium type experiments instabilities leading flips from alignment vice versa. An diagram showing position in amplitude-frequency space derived experimentally suggesting a consistent phenomenological picture phenomena systems under shear.
