摘要：

Combinatorial gradient techniques are used to map the morphology dependence of thin symmetric diblock copolymer films on film thickness and substrate surface energy. An inversion from symmetric to anti-symmetric lameller morphology occurs with a progressive change in surface energy. An intermediate neutral region is found between these limiting types of ordering. The width omega of this transition energy range scales as a power of copolymer mass M, omega proportional to M-1.9.
