ソフトマター物質科学の基礎研究としての高分子とその中性子小角散乱研究の意義について

  We highlight that polymer systems provide extremely good model systems for basic researches on soft-matter physical science. Their inherently large characteristic space-time scale enables us to elucidate the space-time organization of self-assembling processes via phase transitions in such a level that cannot be easily attained by small-molecule systems having small space-time scales. We emphasize also the fact that SANS studies are crucial in elucidating a whole spectrum of hierarchical structures of soft-matters and their responses to external stimuli. As an example, we reviewed some experimental results on space-time organization of phase-separating structures during spinodal decomposition of dynamically symmetric molecular mixtures and discussed universality in this context between polymers and small molecules.
