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> Haoyue Shen, Masashi Otaki, Hiromasa Goto ##submission.copyrightStatement## http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/17 Wed, 16 Jan 2019 00:00:00 +0000 Simultaneous Polymerization-dyeing for Helical Vessels via Oxidative Coupling with Bach Reaction http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/18 <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> Kyoka Komaba, Hiromasa Goto ##submission.copyrightStatement## http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/18 Wed, 24 Jul 2019 00:00:00 +0000 An Attempt of Double Step Polymerization of 3,4-Ethylenedioxythiophene in Cholesteric Liquid Crystal http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/19 <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> Naoto Eguchi, Hiromasa Goto ##submission.copyrightStatement## http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/19 Thu, 25 Jul 2019 00:00:00 +0000 Conductive polymer composites prepared in volcanic spring water http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/21 <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> Akiko Yatsu, Hiromasa Goto ##submission.copyrightStatement## http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/21 Wed, 27 Nov 2019 00:00:00 +0000 Isothianaphthene-Based Polymer with Triple Chiral Side Chains http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/22 <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> Kyoka Komaba, Hiromasa Goto ##submission.copyrightStatement## http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/22 Fri, 13 Dec 2019 00:00:00 +0000 An Attempt to Prepare Flexible–Strong Conductive Fiber with Bagworm Silk http://ojs.tulips.tsukuba.ac.jp/index.php/futurum/article/view/24 <p>Bagworm silk is the strongest biofiber to date. In this research, we prepared bagworm silk/polypyrrole<br>composite by oxidative polymerization as an attempt for preparation of flexible–strong textiles.
