A chiral liquid crystal blend system (LC-blend) of octyloxycyanobiphenyl (8OCB)/DM9CB was prepared, although DM9CB shows no liquid crystal phase alone at room temperature. The LC blend shows a chessboard-like texture under polarizing microscopy (POM) observations at 43 ℃. This chessboard-like texture is assigned to smectic A phase with layer structure. Electrochemical polymerization in this LC-blend system produces π-conjugated polymer having smectic order.</p> 2019-01-16T00:00:00+00:00 ##submission.copyrightStatement## Simultaneous Polymerization-dyeing for Helical Vessels via Oxidative Coupling with Bach Reaction 2019-08-09T05:24:12+00:00 Kyoka Komaba Hiromasa Goto <p>Azo dyes are essential to our lives and are synthesized by coupling reactions. In this research, we carried out dyeing of helical vessels with an azo polymer. The polymer thus synthesized in this study was characterized with infrared absorption and UV-vis absorption spectroscopy measurement. We observed the surface structure of the helical vessels coated with the azo polymer with optical microscopy and scanning electron microscopy (SEM).</p> 2019-07-24T00:00:00+00:00 ##submission.copyrightStatement## An Attempt of Double Step Polymerization of 3,4-Ethylenedioxythiophene in Cholesteric Liquid Crystal 2019-08-09T05:24:32+00:00 Naoto Eguchi Hiromasa Goto <p>Double step polymerization combining chemical oligomerization and electrochemical polymerization of 3,4-ethyelenedioxythiophene was carried out in cholesteric liquid crystal to produce optically active poly(3,4-ethylenedixoythiphene). Polarizing optical microscopy was carried out to investigate the polymer film.</p> 2019-07-25T00:00:00+00:00 ##submission.copyrightStatement## Conductive polymer composites prepared in volcanic spring water 2019-12-13T02:33:41+00:00 Akiko Yatsu Hiromasa Goto <p>Polyaniline (PANI)/vinylon composite was prepared with 2-step process.The composite structure was confirmed with the FT-IR. PANI/spider silk composite was synthesized in volcanicspring water. The preparation of the composite can be carried out with no addition of sulfuric acid because natural acid type volcanicspring water functions as acid reagent for the polymerization reaction. This polymerization is promising for industrial applications for production of polyaniline.</p> 2019-11-27T00:00:00+00:00 ##submission.copyrightStatement## Isothianaphthene-Based Polymer with Triple Chiral Side Chains 2019-12-13T04:44:19+00:00 Kyoka Komaba Hiromasa Goto <p>Methine bridged conjugated polymers have low-bandgaps. This paper reports synthesis of methine-bridged type polyisothianaphthene bearing triple optically active substituents. We introduce chirality to the polymer. The polymer expects three advantages 1) main-chain low-bandgap, 2) isothianaphthene monomer repeat unit to show effective low-bandgap, 3) and good film forming property with chirality through good molecular packing. Infrared and UV-vis optical absorption measurements are carried out to confirm molecular structure.</p> 2019-12-13T00:00:00+00:00 ##submission.copyrightStatement## An Attempt to Prepare Flexible–Strong Conductive Fiber with Bagworm Silk 2020-11-10T07:30:51+00:00 Kyoka Komaba Noriko Hayashi Eiji Tokgawa Hiromasa Goto <p>Bagworm silk is the strongest biofiber to date.
