Simple self-assembly techniques were developed to fabricate non-spherical polymer particles, where surface composition and shape can be tuned through temperature and the choice of non-solvents. A series of amphiphilic polystyrene-b-poly(2-ethyl-2-oxazoline) block copolymers were prepared and through solvent exchange techniques using varying non-solvent composition a range of non-spherical particles were formed. These techniques present new tools to engineer the self-assembly of non-spherical polymer particles.
