    ABSTRACT

    In this paper, we aimed to synthesize polysulfide with pendant methacryloyl groups in the side chain. They are expected to have great potential for various applications as UV‐curable higher‐refractive‐index resins. Thiiran‐2‐ylmethyl methacrylate (TMA) could be synthesized by the reaction of glycidyl methacrylate with thiourea using conc. H<sub>2</sub>SO<sub>4</sub> as a catalyst. Selective ring‐opening polymerization of TMA could be achieved using CuCl<sub>2</sub> as an initiator in CHCl<sub>3</sub> at 25°C, yielding the corresponding polysulfide polyTMA<sub>(MA)</sub> with pendant methacryloyl groups in the side chain in high yield. The copolymerization of TMA and phenoxypropylene sulfide (PPS) was also performed to give poly(TMA<sub>(MA)m</sub>‐co‐PPS<sub>n</sub>) with M<sub>n</sub> = 1330–1940 (M<sub>w</sub>/M<sub>n</sub> = 1.03–2.02) in high yields. The UV‐curing reaction of thin films of polyTMA<sub>(MA)</sub> and poly(TMA<sub>(MA)m</sub>‐co‐PPS<sub>n</sub>) containing a photo‐radical initiator proceeded smoothly under UV light, quantitatively affording the corresponding cured thin films. The refractive indices of the thin films before and after UV irradiation were determined by ellipsometry. Among them, poly(TMA<sub>(MA)22</sub>‐co‐PPS<sub>78</sub>) showed the highest refractive index value (n = 1.763) after the UV‐curing reaction.

    Abstract

    Tungsten oxide‐mica composites were prepared by adding different amounts of commercial mica (alumina silicate) in order to provide high luster to electrochromic coatings. The mechanical stability was sustained for up to 50 weight % mica for application in aqueous medium. The electrochemical properties, coloration, and luster were investigated. The luster of the composites increased roughly linearly with increased mica content and was retained after coloration. The addition of 10 weight % mica was found to be optimal with respect to the compromise between electrochromic coloration and pearlescent luster. This is, to the best of our knowledge, the first report on the preparation and characterization of WO<sub>3</sub>‐mica inorganic composites with high luster in both bleached and colored states.

    Grant amount:\4290000 ( Direct Cost: \3300000 、 Indirect Cost:\990000 )

    We address the preparation of three-dimensionally nanostructured inorganic materials by biomimetic aqueous route.
    We achieved the morphological control of WO3 film materials by an aqueous solution process. WO3 hydrate layers were prepared on glass substrates via heterogeneous nucleation from aqueous solutions, and then thermally converted to monoclinic WO3 films. Micron-scale platy-particle WO3 films were obtained from WO3 hydrate layers. Hureaulite (Mn5(PO3OH)2(PO4)2 4H2O) crystals were obtained from the aqueous suspensions containing the as-deposited phases. The crystal size of the hureaulite products increased by increasing heating temperature and by addition of citric acid. Large hureaulite single crystals of ca. 500 μm in size was prepared from the precursor solutions containing citric acid.
    These results are beneficial for the development of novel aqueous solution techniques for making nanostructured inorganic materials.

    Grant amount:\16900000 ( Direct Cost: \13000000 、 Indirect Cost:\3900000 )

    We improved the spontaneous pattern formation induced by Benard-Marangoni convection triggered by solvent evaporation. Here, we attempted to control more precisely the pattern size by the molecule design of the precursor materials of sol-gel-derived ceramic films. Cell-like patterns of 1.0-1.5 μm in height and of ca. 20 μm in width were spontaneously formed on the surface of ceramic films prepared by sol-gel dip-coating process. We found that the size of the cell-like patterns induced by Benard-Marangoni convection increased with increasing molecule size of the precursor mateirals, which could be caused by the higher surface tension. Moreover, novel pattern formation was observed on ceramic films obtained from metal-acetylacetonate complexes, where dendrite patterns formed with decreasing substrate withdrawal speed. These results are beneficial for the development of novel self-organization triggered by solvent evaporation.

    Grant amount:\3900000 ( Direct Cost: \3000000 、 Indirect Cost:\900000 )

    Organically modified polyoxometalates were prepared by hydrolyzing metal alkoxides in the presence of chelating agents like benzoylacetone (BzAc), followed by concentration and drying. The softening temperature was found to be affected by the molecular weight of the polymerized species, which are varied with the amounts of the chelating agents and of the water for hydrolysis. Structural analysis based on pair distribution function suggested that the BzAc-modified polyoxotitanates are composed of TiO6 octahedra that are liked by corner- and edge-sharing. The BzAc-modified polyoxotitanates showed glass transition in their low-temperature TMA and DSC curves, suggesting that such organically modified polyoxometalates could be a new class of glassy materials.

    Grant amount:\17940000 ( Direct Cost: \13800000 、 Indirect Cost:\4140000 )

    We conducted experimental studies on our technique that allows the fabrication of ceramic thin films on plastic substrates. First, even when fired at temperatures higher than 600℃, the ceramic thin films could be transferred to plastic substrates. Second, we noticed that there is an optimized thickness of release layers that enables successful transfer of ceramic thin films onto plastic subsrates. Third, plastic substrates with polar groups were demonstrated to have good adhesion, while those with no polar groups have poor adhesion. However, even such plastic substrates with no polar groups exhibit good adhesion when subjected beforehand by UV/ozone treatment, which oxidizes the substrate surface. Finally the degree of plastic substrate bending that is not accompanied by film cracking was found to decrease with increasing firing temperature.

    We suggested the spontaneous pattern formation induced by Benard-Marangoni convection as a novel patterning process of sol-gel-derived ceramic films. Cell-like micropatterns were spontaneously formed on the surface of silica films prepared via dip-coating process, where the surface patterns were linearly arranged parallel to the substrate withdrawal direction. Such highly-ordered micropatterns were achieved by Benard-Marangoni convection and the unidirectional flow of the coating solution on the substrate during dip-coating. We found that the size of the cell-like patterns induced by Benard-Marangoni convection increased with increasing coating temperature and surface tension of coating solutions. Moreover, novel pattern formation induced by capillary force was observed with decreasing substrate withdrawal speeds. These results are beneficial for the development of novel self-organization triggered by solvent evaporation.

    Silica thin films were prepared from perhydropolysilazane (PHPS) via exposure to the vapor from aqueous ammonia. PHPS-derived silica films had higher hardness, chemical durability and adhesion to plastics than alkoxide-derived silica gel films. Polycarbonate plates were coated with polymethylmethacrylate, and then with PHPS, followed by the exposure to the vapor from aqueous ammonia, which successfully increased pencil hardness from under 10B to H - 2H.

    本研究では、生物が行なう無機材料合成(バイオミネラリゼーション)を模倣することで、三次元ナノ構造を有する機能性酸化物を合成することを目的とした。リチウム二次電池電極として優れた電極特性を持つことが知られている酸化スズ(SnO)、マンガン酸リチウム(LiMn_2O_4)、リン酸鉄リチウム(LiFePO_4)を作製し、その電極材料としての優位性の検討を行なった。
    LiMn_2O_4では、我々のグループが以前に報告したゲルマトリクス中における結晶成長の手法を利用することでMnCO_3ナノ構造体を作製し、それをLiCO_3と共に焼成することでLiMn_2O_4ナノ構造体を作製することに成功した。本手法で得られたLiMn_2O_4ナノ構造体をリチウム二次電池正極に用いることで、0.5A/gの電流値の充放電特性において電極耐久性の向上が見られた。
    SnOおよびLiFePO_4では、それぞれの中間体であるSn_6O_4(OH)_4、Fe_3(PO_4)_2を溶解再析出によって目的物質へと変化させる際の反応条件を調整することで、ナノ構造の制御を行なった。SnO結晶はSn_6O_4(OH)_4を酸性溶液中でエージングすること、ピラミッド状、メッシュ状、花弁状といった様々な形状を有するSnO結晶の作製に成功した。一方、LiFePO_4においては、Fe_3(PO_4)_2をLiOH溶液を用いて180℃で水熱処理することで、ナノロッドが方位を揃えて集積した櫛状粒子が得られた。
    上記の研究成果について国際会議2件(LiMn_2O_4,SnO)、国内学会1件(LiFePO_4)の学会発表を行なった。また、SnOに関しての成果をまとめた論文が学術雑誌Langmuirに掲載され、関連した論文を2件投稿中である(2009年3月現在)。上記の研究以外にも光触媒に関する論文を共著で発表した。

Devising educational methods

  • 学生実験を主に担当しており(1年次「フレッシュマンゼミナール:化学実験入門」、2年次「マテリアル科学実験1,2」、3年次「マテリアル工学実験1,2」)、実験前に実験概要や基礎的な知識の要点を提示し、学生に課題を明確に示した上で実験に行うようにしている。 また、実験終了時に課題レポートに最低限のまとめるべき内容を指示し、学生がレポートのまとめ方を学べるように意識した指導をしている。その際に、指示した内容に加えて各自で自由課題に取り組むように促し、学生が自主学習の意識を忘れないように配慮している。 これらの指導方法は、授業評価アンケートにおいて、この方法が理解を深めるのに非常に役立っているとの感想が多い。
