With the addition of small molecules to emulsion droplets containing block copolymers, anisotropic convex lens-like particles with hexagonally stacked cylindrical domains can be readily achieved by using a single surfactant to create a neutral interface for both blocks.

NanoPDF64is a tool designed for structural analysis of nanocrystals based on examination of powder diffraction data with application of real-space analysis. The program allows for fast building of models of nanocrystals consisting of up to several hundred thousand atoms with either cubic or hexagonal close packed structure. The nanocrystal structure may be modified by introducing stacking faults, density modulation waves (i.e.the core–shell model) and thermal atomic vibrations. The program calculates diffraction patterns and, by Fourier transform, the reduced pair distribution functionsG(r) for the models. ExperimentalG(r)s may be quantitatively analyzed by least-squares fitting with an analytical formula.

Hexagonally Ordered

Flow can transfer the microphase separated morphology of block copolymers into a state of global order. For tri-block copolymers with cylindrical domains, this has been demonstrated by Folkes et al. (1973) and Hadziioannou et al. (1979). who established the existence of ‘single crystals’ of hexagonally ordered cylinders with uniform director throughout a sheared sample. The director is aligned with the shear direction. In this study, we investigate the flow induced ordering of cylindrical domain structure at increasing levels of shear.
