Directed Self-assembly of High-Molecular-Weight Block Copolymer Films

ORAL

Abstract

The solvent-vapor annealing of block copolymer (BCP) films facilitates the mobility of highly entangled polymer chains, or the path-way barriers to the formation of well-ordered structures. In this study, the microdomain orientation of BCP films has been studied by in-situ grazing incidence small angle x-ray scattering (GISAXS), atomic force microscopy (AFM), and scanning electron microscopy (SEM). We demonstrate the rapid evolution of a perpendicularly oriented lamellar morphology in high-molecular-weight (up to 1,000,000 g/mol) block copolymer films, to achieve topographically patterned BCP substrates.
