Figure 3: Statistical evaluation of disk-cylinder hybrid morphologies.
From: Disk-cylinder and disk-sphere nanoparticles via a block copolymer blend solution construction
Column graph shows the number percentage of disk-cylinder multigeometry nanoparticles of slightly different morphology (produced from analysis of 100 particles in OsO4 stained TEM image). Blue, red and green columns are corresponding to populations of round disk, oblate disk and tailed-disk, respectively. The sizes of the bilayer section of the particles were calculated from the area of dark PAA-b-PI disk region in the particles by an equation of bilayer size=2*[(Area of PAA-b-PI bilayer)/π]1/2. The bilayer size is equal to the diameter of the central dark region of PAA-b-PI assuming a round disk section to simply give a measure of size comparison between particle disk sections. Insert images are OsO4 stained TEM showed the selected particle morphologies in the same sample of round disk (a), oblate disks (b,c) and tailed disks (d–h) of different bilayer sizes indicated by dash lines. Scale bar, 50 nm.
