| Research Group on Polymer Surface and Interface: the Growing Applications and the Challenges for the Future |
Tomohisa NAKAMURA and Takashi NISHINO |
| <Abstract>The
Research Group on Polymer Surface and Interface deals with subjects on
surfaces and interfaces of polymers and related materials. It has been
run by collaboration between researchers on preparing or modifying polymer
surfaces and those on surface analysis. The committee members from academic
field and industrial field are cooperating to provide timely information
on polymer surface and interface and the place to exchange ideas for
promoting research and development activities. Keywords: Polymer Surface / Interface / Functional Materials / Surface Analysis / Modifying Polymer Surfaces |

| Research Group on Adhesion and Coatings | Noriyuki YONEZAWA |
| <Abstract>As
one of the most important material technologies for industry and human
life, adhesion and coatings have been made use of almost all solid daily
goods, architectures, electronics, automobiles, bottles and cans of foods
and so on. However, the advanced technology is urged by necessity in
answer to the request such as reduction of vaporizable organic compounds
(VOC) and elimination of carbon dioxide. The researchers in polymer sciences
are invited to participate in research activities for the field of such
complex material technology to solve the big problem by making full use
of the polymer scientific insights leading the reform of the material
paradigm. Keywords: Adhesion / Coating / Vaporizable Organic Compounds (VOC) / Material Paradigm |

| <Abstract>This
research group was founded in 1991 and has been growing with the progress
of electronics and information technologies. It covers the latest topics
such as micro- and nano-fabrication processes, packaging technologies,
photopolymers and resists, high thermo-durable functional materials such
as photo-sensitive polyimide, and materials for photonics and other organic
and inorganic materials for, e.g., 2-D and 3-D nano-fabrication. Keywords: IT / Microelectronics / Photonics / Lithography / Photopolymer / Resist / Nanotechnology |

| Research Group on Photonics Polymers | Yasuhiro KOIKE |
| <Abstract>Photonics
polymers have been widely used as materials for photonics devices such
as optical disks, lenses, optical fibers, and optical films and light
guide plates for displays. However, we think that potential of photonics
polymers have not been fully extracted and discussion among researchers
in the fields of chemistry, processing, photonics and electronics is
important for further development of the filed of photonics polymers.
This research group aims to enhance the discussion and develop human
resources in this field. Keywords: Photonics Polymers / Plastic Optical Fiber / Display / Optical Disk / Fiber to the Display / Lens / Communication |

films are widely used for packaging application in our life, and their
application has been expanding with high quality and multi-functionality.
The research group focuses on not only plain film itself but also film
manufacturing, film converting technology like coating or surface treatment,
raw materials suppliers, functional film manufacturing industries for
FPD and nano-technology applications. Keyword: Plastic / Film / Stretching / Coating / Packaging / Flat Panel Display / Fuel Cell Multi Layer / Imaging / Gas Barrier |

| Research Group on Inorganic Polymers | Kimihiro MATSUKAWA |
| <Abstract>“Research
Group on Inorganic Polymers” intends discussing not only pure inorganic
polymers but also the scientific area where polymers including “Inorganic
Substance” are concerned. The activity of the research group will stimulate
an information exchange and supply a hint for the development of new
materials. Recently, organic-inorganic nano-hybrid materials have been
mostly attracted for the advanced applications. Keywords: Inorganic Polymer / Organic-Inorganic Hybrid / Organometal / Ceramics / Nano-Functional Materials / Inorganic Nano-Structure |

| Research Group on Supramolecules | Kimihisa YAMAMOTO |
| <Abstract>This
research group was derived from Research Group on Macromolecular Complexes
established in 1976, which had supplied wide information about macromolecular
complexes. This research group was renamed to Research Group on Supramolecules
on April first in 2006, commemorating the 30th anniversary of the founding.
“Supramolecules” deserve much attention as new materials for advanced
nanotechnologies and have received a great amount of scientific and technological
interest for the next generation. Keywords: Supramolecules / Macromolecular Complexes / Metal Complex / Organic-Inorganic Hybrid Materials / Self-Assembly / Nano-Organized System / Super-Hierarchical Structures / Molecular Programming / Nano-Technology |

| Double Network Hydrogel with High Modulus and
Toughness: A Novel Material for Load-Bearing Soft Tissues |
Jian Ping GONG |
| <Abstract>Hydrogels
attract attention as excellent soft & wet materials. However, common
hydrogels are mechanically too soft and brittle to be used as load-bearing
materials. By mimicking the structure of the articular cartilage which
is one of the native tough hydrogels, Double Network hydrogel (DN gel)
with extremely high mechanical performance has been developed. DN gels,
consisting of rigid and brittle polyelectrolyte network as the 1st component
and soft and ductile neutral network as the 2nd component, exhibit 0.1-1
MPa of elastic modulus, 60 MPa of compressive fracture stress, 3000% of
tensile strain, and 2500 J/m2 of fracture energy. Such a tough hydrogel
has an excellent mechanical compatibility with load-bearing soft tissues
such as articular cartilages. Keywords: Hydrogel / High Elasticity / High Strength / Double Network Gel / Toughness / Polyelectrolyte / Mechanical Compatibility / Artificial Cartilage |

| Recent Development in Characterization and Physical Properties of Ring Polymers | Yutaka OHTA and Atsushi TAKANO |
| <Abstract>Although
numerous works on physical properties of ring polymers were made for
three decades, most of polymer samples used so far were not pure enough.
Recently new HPLC technique with high resolution has provided rigorous
characterization of rings. In this article, recent developments in characterization
and physical properties of well-characterized ring polymers are described. Keywords: Ring Polymer / Solution Property / Bulk Property / Viscoelastic Property / Interdiffusion |
