Abstract

Diblock copolymers are composed of two chemically distinct chains covalently bonded together at one end. We have discovered how to control the orientation of diblock copolymer microdomains (made up of nanoscopic cylinders, or lamellae) in thin films. To do this, we eliminated all preferential interfacial segregation of the components by anchoring random copolymers, composed of identical monomers to the diblock copolymer, to both interfaces of the film. The composition of the random copolymer is tailored to balance interactions between the segments of the copolymer and the interfaces.
