Influence of BCP molecular weight on the shape anisotropy of ellipsoidal PS-b-P2VP nanoparticles with axially stacked lamellae obtained for neutral wetting conditions 3:1 ratio of HO-CTAB:CTAB (X=0.75): a) TEM images of similar sized (L ~ 550 nm) BCP nanoparticles obtained from PS-b-P2VP diblock copolymers with molecular weights of (i) 20k-20k, (ii) 40.5k-41k and (iii) 102k-97k; b) Plots of experimental ( ● dots) and theoretically (▬lines) predicted aspect ratios (L/D) in dependency on the long axis (L) for representative populations of the 3 respective diblock copolymer molecular weights.
