摘要：
The orientation of cylindrical and lamellar micro-phase separated structures of some block copolymers (BCP) in thin films was investigated by grazing incident small-angle X-ray scattering and atomic force microscopy. The thin films were made from solution using selective solvents for the major component of the BCP. The spherical structure was arrested initially in the film with a thickness of 500 nm(-1) mu m. Solvent annealing, using common solvents, induced a morphology transition from spherical to a vertically oriented cylindrical (lamellar) structure. A neutral solvent for both components in the BCP was found to be effective for the perpendicular orientation of the micro-domains. (C) 2014, The Society of Polymer Science, Japan
