The organic solvent plays an important role in the preparation of block copolymer particles from solvent-evaporative emulsions. Herein, we report the solvent effects leading to a variety of different 3D structures in the self-assembly of the amphiphilic block copolymer, polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP). The solvent selectivity, polarity, volume fraction of PS-b-P4VP, and surfactant concentrations affected the degree of the interfacial instability of block copolymer emulsion, where an increase in the interfacial instability led to a distinct morphological transition of PS-b-P4VP particles from spheres to porous particles, capsules, and micelle structures. |
