関 隆広・永野 修作 Takahiro SEKI and Shusaku NAGANO |
| ＜要旨＞ 高分子薄膜は通常，溶媒塗布により調製される。しかし，規則構造や階層構造が機能発現に重要な役割を果たす膜系では，分子充填や構造形成の配向を意のままに制御できる手法の開発が望まれる。ここでは，界面との相互作用を積極的に利用した構造形成と配向誘起に関するアプローチを概観し，その意義に触れる。 Keywords: Polymer Thin Films / Orientations / Controls at Interfaces / Block Copolymers / Conjugated Polymers / Photoresponsive Polymers / Surface-Grafted Chains / Organic-Inorganic Mesostructures |

| 界面の物理化学的性質と接着特性 Effects of Physico-Chemical Properties on Performance of Adhesive Bondings |
越智 光一 Mitsukazu OCHI |
| ＜要旨＞ 接着接合では，被着体と接着剤の界面の特性が最も重要な支配因子となることが多い。この界面では，界面自由エネルギーを最小にするように自発的に界面組成が変化する。また，接着過程での接着剤の収縮にともなって界面には応力が蓄積される。このような接着界面での組成の変化や蓄積された応力が接着接合部の性能におよぼす影響を，接着の界面化学に基づいて紹介する。 Keywords: Adhesive Bonding / Interface / Interfacial Free Energy / Dynamic Wetting / Internal Stress |

| パーフルオロアルキル基を含むポリマーの表面構造解析 Surface Characterization of Perfluoroalkylated Polymers |
杉山 賢次 Kenji SUGIYAMA |
| ＜要旨＞ A variety
of block copolymers and end-functionalized polymers containing perfluoroalkyl
(RF) groups were precisely synthesized by the living anionic polymerization
technique. The resulting polymer films were carefully characterized with
the point in view of constructing a fluorine rich surface depending on
the chemical structure of the polymer. Remarkable enrichment of the RF
groups at the dry surface was indicated by the surface analyses of these
polymer films. Interestingly, surface reconstruction corresponding to
the environmental change was observed when the RF groups were introduced
in hydrophilic polymer. Keywords: Anionic Polymerization / Block Copolymer / End-Functionalized Polymer / Environmental Change / Hydrophobicity / Oleophobicity / Perfluoroalkyl Group / Surface Construction |

| ブロック共重合体薄膜におけるミクロドメインの直立配向と長距離秩序構造制御 Vertical Orientation and Long Range Ordering of Microdomains in Block Copolymer Thin Films |
早川 晃鏡 Teruaki HAYAKAWA |
| ＜要旨＞ Microdomains
such as lamellae and cylinders in block copolymer thin films that are
oriented perpendicular to the underlying substrate have advantages in
pattern transfer over spheres or parallel cylinders because of the higher
aspect ratio of the resulting template and the vertical side walls. Herein,
current approaches for orientation and long range ordering of the microdomains
are described. Keywords: Block Copolymer / Microdomain / Thin Films / Vertical Orientation / Long Range Ordering / Directed Self-Assembly |

| ブロック共重合体微粒子中の凝集構造 Nanostructures in Block-Copolymer Particles |
藪 浩 Hiroshi YABU |
| ＜要旨＞ Unique microphase
separation structures, different from bulk structure, are found in block-copolymer
particles, which are considered three-dimensional confinement spaces.
Block-copolymer particles were prepared by the self-organized precipitation
(SORP) method. Electron microscopy revealed that the microphase separation
structures in the particles changed from lamellae to various unique morphologies
depending on the size of particles. Keywords: Block-Copolymers / Confinement / Microphase-Separation / Particles / Self-Organization / Precipitation |

星野 大樹 Taiki HOSHINO |
| ＜要旨＞ X-ray photon
correlation spectroscopy (XPCS) is a powerful technique to study interfacial
dynamics of soft materials. In this manuscript, recent XPCS studies for
interface dynamics are briefly reviewed. Furthermore, an XPCS study of
the dynamics of polymer grafted nanoparticles in polystyrene matrix is
presented. Keywords: X-Ray Photon Correlation Spectroscopy / Dynamics / Polymer Grafted Nanoparticle |

| ナノ触診技術による高分子表面・界面の研究 Nanopalpation Technique for Polymeric Surfaces and Interfaces |
中嶋 健 Ken NAKAJIMA |
| ＜要旨＞ Nanopalpation
allows us to map physical properties such as Young's modulus, adhesive
energy and energy dissipation at nano-scale, which is realized by assuming
the atomic force microscope's sharp probe as a doctor's finger. The comparison
between this technique and the conventional tapping-mode operation was
employed by using a block-copolymer type thermoplastic elastomer as a
model specimen. Keywords: Nanopalpation / Atomic Force Microscope / Young's Modulus / Energy Dissipation / Block Copolymer |

| 融合マテリアル：バイオミネラリゼーションを超える機能材料創成へ向けて Fusion Materials: Toward the Development of New Functional Materials Overcoming the Limitations of Biomineralization |
加藤 隆史 Takashi KATO |
| ＜要旨＞ It is important
to develop new sophisticated organic/inorganic hybrid materials to create
a sustainable society where materials are in harmony with the environment.
These materials should be produced through processes with efficient use
of energy and resources. To mimic biomineralization is an attractive
strategy for the preparation of organic/inorganic hybrid materials. Sophisticated
hybrid materials such as teeth, bones, seashells and exoskeletons are
produced by biomineralization and they exhibit excellent properties.
Molecular control is a key in biomineralization. In this process, biomacromolecules
such as proteins and polysaccharides precisely control the crystallization
of inorganic substances. An innovative new research area for futuristic,
highly functional, and environmentally friendly materials will be realized
by the fusion of functional inorganic materials with state-of-the-art
organic materials. Keywords: Self-Organization/ Biomineralization / Fusion Materials / Hybrid Materials / Supramolecular Chemistry / Self-Assembly / Liquid Crystals / Crystal Growth |
