  • LIQUID CRYSTAL POLYMER FILM, LIQUID CRYSTAL POLYMER FILM WITH CONDUCTOR LAYER, AND MULTILAYER SUBSTRATE
    Publication number: 20240076552
    Abstract: A liquid crystal polymer film that includes: a benzene ring; a naphthalene ring; and a carboxymethyl group, wherein, in a 13C-NMR spectrum of a liquid crystal polymer film decomposed with supercritical methanol, an integral value CA of a peak derived from the benzene ring, an integral value CB of a peak derived from the naphthalene ring, and an integral value CC of a peak derived from the carboxymethyl group satisfy (CA+CB)/CC of 1.35 to 1.65.

  • Electrically conductive polyrotaxane
    Patent number: 8613611
    Abstract: The conductive polyrotaxane of the present invention contains an electron-accepting cyclic molecule in each of its repeating unit. Since the electron-accepting cyclic molecule remains stable because of molecular interaction with a ?-conjugated oligomer molecule, the electron-accepting cyclic molecule is not dissociated during rotaxane polymerization reaction, and thus a conductive polyrotaxane of stable quality can be obtained.
    Type: Grant

    Assignee: National Institute for Materials Science
    Inventors: Taichi Ikeda, Masayoshi Higuchi, Dirk G. Kurth
