Abstract

Combinatorial gradient techniques are used to map the thin film morphology dependence of symmetric diblock copolymers as a function of film thickness and substrate surface energy. An inversion from symmetric to asymmetric lamellar morphology is observed as a function of surface energy and a broad transition region is found connecting these limiting types of ordering, whose width w scales as a power of copolymer mass M.
