Shear-induced morphological change in PP/LLDPE blend
The morphology of a PP/LLDPE blend (50:50) by phase dissolution at high shear rate combined with dynamic packing injection molding at low shear rate was investigated by atomic force microscopy. Phase dissolution under high shear rate is manifested by a co-continuous two-phase structure that could be broken down to an island-like structure when a low shear rate is applied via dynamic packing injection molding or simply by manual deformation.
