The role of cooling rate in crystallization-driven block copolymer self-assembly

This study focused on the effect of cooling rate following a heating step on the micelle morphologies formed by a series poly(ferrocenyldimethylsilane) (PFS) crystalline-coil block copolymers (BCPs) in solution. We employed transmission electron microscopy (TEM) (i.e. Figure 3) to determine the micelle morphologies. In one co-self-assembly experiment, we labeled a homopolymer sample with a red fluorescent dye and a BCP with a green fluorescent dye and used the laser confocal fluorescence microscopy (Figure 4) to distinguish the distributions of each polymer component. We include the 1H nuclear magnetic resonance (NMR) spectra (i.e., Figure S5) used to determine the extent of dye incorporation. These spectra files can be opened by the software MestReNova or others that are applicable. The length measurements were made using ImageJ. We attach the data and people can use Microsoft Office Excel or the software Origin 2020 to examine it.
