Study of the crystallisation under flow of star-polymer in the flow direction to probe bcc-to-fcc transition
Star polymers are ultrasoft colloidal particles obtained by tethering a number f of linear polymer chains (arms) to a common center. It has been shown that the application of shear promotes cooperative rearrangements of the star polymer and arm disengagement leading to crystal formation. RheoSANS experiment using a common cop-and-bob geometry has shown that the softness and morphology of the object apparently play an important role on the nucleation process and crystallisation kinetics [Phys. Rev. Lett. 120, 078003 (2018)]. Furthermore, computer simulations has shown that a bcc-to-fcc transition is promoted under constant flow. To further investigate this phenomenon, here we propose to use the 1,2 shear cell only available on D22 to measure the behaviour of star polymers with different softness under flow. As indicated by computer simulated scattering patterns, the emergence of the bccc-to-fcc transition can be detected only in the flow plane.
