We report a versatile emulsion-based synthesis for the preparation of nanometer-sized dumbbell-shaped particles that contain two chemically different patches. One patch consists of solely polystyrene and is therefore chemically inert toward most chemical reactions. The other patch contains reactive surface chlorine groups. To achieve this, we prepared seed particles with a chlorinated surface that were transformed into dumbbell-shaped particles by introducing a liquid styrene protrusion on the… CONTINUE READING
