Abstract: | Block copolymers (BCPs) are known to self-assemble into various structures. In particular, crystallization-driven self-assembly (CDSA) strategies revealed a high potential for expanding the scope of obtainable structures at the nanometer length scale. Herein, we report the characterization of different self-assembled structures of a series of amorphous-crystalline BCPs poly(dimethyl silacyclobutane)-block-poly(2-vinyl pyridine) (PDMSB-b-P2VP). The polymers and their structure formation in different solvents were analyzed, and their response toward different solvent vapors and temperatures in the deposited state was evaluated by transmission and scanning electron microscopy (TEM, SEM) and atomic force microscopy (AFM). The influence of additional solvents, temperature, and ultrasonication on colloidal dispersions was investigated with additional dynamic light scattering (DLS) and differential scanning calorimetry (DSC) experiments. Finally, the polymer was introduced to a colloidal confinement by employing the solvent evaporation method in the presence of cetyl-N,N,N-trimethylammoniumbromide (CTAB) or 16-hydroxycetyl-N,N,N-triethylammoniumbromide (CTEAB-OH) as surfactants, resulting in a plethora of additional colloidal structures. |
