ジャーナル フリーBlock copolymers self-assemble into a variety of ordered structures in nanometer scale as a result of microphase separation. Such nanostructures can be utilized as a template for nanometer scale porous structures. We have succeeded in fabricating nano-scale pores or foams by introducing supercritical carbon dioxide into particular domains of block copolymers. Fluorine containing polymer has affinity toward carbon dioxide and hence fluorine containing block copolymers work ideal template for this technique. Spherical, cylindrical, planar and bicontineous porous sturctures have been fabricated by this technique. We further observed order-order transition of block copolymers while swelling in carbon dioxide by in-situ small angle X-ray scattering, and thus the resulted porous structures are not always similar to the original morphologies of block copolymers.抄録全体を表示PDF形式でダウンロード (1169K) -

ジャーナル フリーStyrenic thermoplastic elastomer (TPS) is used for a broad range of applications because of its functions and performances. Its block-copolymer structure combines the properties of the hard-segment blocks and the soft-segment blocks, resulting in ease of processing and excellent performance characteristics. This paper introduces typical application concepts and solutions of TPS based on actual examples of our styrene-butadiene-styrene block copolymer (SBS) and styrene-ethylene-butylene-styrene block copolymer (SEBS). Especially, we focus on applications for adhesives, asphalt modifiers, resin modifiers, damping materials.抄録全体を表示PDF形式でダウンロード (1929K) -

ジャーナル フリーBlock copolymers spontaneously form such highly ordered self-assembled structures as opals and bright blue wings of morphos do, which provide very promising photonic crystals for non-linear optical devices to establish a ubiquitous society on the basis of high-speed communication. We control the flow of light by understanding and controlling the mechanism of the structures formation. We have succeeded in fabrication of photonic crystals using ultra-high-molecular-weight block copolymers in semi-dilute solutions by addition of non- or highly-selective solvents. Our photonic crystals fabricated here showed high tunability of the periods and morphologies that are applicable to non-linear optical devices because of softness of polymers. In this article, the formation mechanism of highly-ordered microdomain structures in the solutions as well as historical background of optical devices and photonic crystals are reviewed.抄録全体を表示PDF形式でダウンロード (1126K) -

ジャーナル フリーA novel acrylic thermoplastic elastomer (TPE), poly(methyl methacrylate)-block-poly(n-butyl acrylate)-block-poly(methyl methacrylate), was developed by a living anionic polymerization technology. The acrylic TPE has excellent weather-resistance, transparency, flexibility and adhesive property. The applications are now expanding in the fields of pressure sensitive adhesives, molding materials and modifiers.抄録全体を表示PDF形式でダウンロード (3015K)
