The melt morphology is determined using rheology and small-angle neutron and X-ray scattering data in conjunction with dissipative particle dynamics simulations of a model molecule matching the volume fractions of the experimental system. The simulations are used to interpret the scattering data and identify the melt morphology as a new perforated lamellae structure. In this structure the P2VP forms hexagonally perforated lamellae containing close-packed protrusions of PS connecting adjacent lamellae layers of PS. The PI part forms a lining between the P2VP and PS domains constrained by the molecular architecture.Keywords: Dissipative particle dynamics simulation; Experimental system; Molecular architecture; Scattering data; Computer simulation; Microchannels; Scattering; Morphology201110.1021/ma10163142016-02-24
