Miniaturized triblock copolymers have been found to self-assemble into nanostructures that are highly regular in size and shape. Mushroom-shaped supramolecular structures of about 200 kilodaltons form by crystallization the chemically identical blocks self-organize films containing 100 or more layers stacked a polar arrangement.
