The distribution of the added guest molecule in the microstructure and the interfacial structure is examined by using a small angle neutron scattering technique. The characteristic length and the interfacial thickness of the microstructure are deformed in order to optimize the distribution of the guest molecules. The obtained experimental results including the existence of the double gyroid and rhombohedral phases are in agreement with those of the simple model of diblock copolymers.American Institute of PhysicsJournal Articleapplication/pdfhttp://hdl.handle.net/2115/5430https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5430/1/JCP119-7.pdf0021-9606Journal of Chemical Physics1197389138952003enginfo:doi/10.1063/1.1591734Copyright © 2003 American Institute of Physicspublisher
