Size First, Shape Late

Pipette-column settling of onion-sphere and stacked-ellipsoid PS-b-P2VP microparticles

A research poster from the School of Underlying Conditions settles a 1:1 mixed batch of confined-assembly PS-b-P2VP microparticles, onion-lamellar spheres and axially stacked ellipsoids, in a 250 mm pipette column and classifies at least 400 particles per withdrawal by SEM. Whole withdrawals drift only from 50 to 56 per cent ellipsoids over 72 hours, but within the 3.5 to 4.0 µm cut the spheres clear first and the cut is 91 per cent ellipsoids at 48 hours, equal-volume ellipsoids settling at 0.90 of the sphere velocity.
