제목 Kinetic Pathway of Disorder-to-Order Thermal Transition in Diblock Copolymer Thin film
초록 In this study, we investigated the development of the morphology in block copolymer thin film after rapid quenching from the disordered state. Polystyrene-block-polyisoprene (PS-b-PI; Mw = 35.8 k, fPI = 0.67) thin films were spin-coated on silicon wafers. Upon heating this polymer exhibits HPL, DG and Hex morphology in sequence before melting. In-plane morphology of the thin film was investigated by using transmission electron microscopy (TEM), grazing incidence small-angle X-ray scattering (GISAXS). HPL phase appears a kinetically favored phase to be formed from the disordered state in thin film.
