TEM analysis of phase separated controlled by the particles sizes formed by PS-b-P2VP-b-PS triblock copolymers a) TEM image of P2VP sphere morphology in PS matrix occurring in a 400nm diameter nanoparticle. b) Onion-like morphology after thermal annealing of the 400 nm particle displayed in a). c) TEM image of triblock copolymer particle (250 nm) formed after the addition of 14 %wt water. d) Disordered lamella-type structure after thermal annealing the 250 nm particles shown in c). P2VP phase is stained with iodine.
