  We investigate the effect of polydispersity on the properties of curved
linear brushes in good solvent and for molten brushes. To this end, we extend
the strong stretching theory for polydisperse brushes to curved geometries and
investigate the polymer chain end profiles, bending moduli and other properties
for experimentally relevant polymer chain length distributions of the
Schulz-Zimm type. We also investigate the properties of End Exclusion Zones
(EEZ) that may appear in convex geometries under certain conditions, and show
that their position in the brush can be engineered by careful selection of the
polymer length distribution. Lastly, we propose a method to engineer chain end
profiles by engineering the polymer length distribution.
