Grazing Incidence Small Angle X-ray Scattering Studies on Structures of Block Copolymers in Nanoscale Thin films

摘要

Thin films of block copolymers have recently received considerable attention because of their potential nanofabrication applications.2 In these applications, controlling the morphology of the block copolymer films, particularly the orientation and ordering of the phase-separated microdomains, is essential. In the thin film state, however, surface-block interactions and the confinement effect related to film thickness give rise to morphologies that differ from those in the bulk.
