Research Group on Imaging Display and Materials Niro WATANABE
<Abstract>This research group was established in 1957, and has focused on discussing technology perspectives and technology road maps in the area of “printing, information media and display”, among industry, university and government. The first organic semi-conductors in applied devices are ready to take a big leap. For those organic semi-conductor devices, including low-cost OLED,E-paper, memories and solar battery are now active areas of R&D.

Nanobiofunctions on Polymer Interfaces Kazuhiko ISHIHARA
<Abstract>This article reviews the recent researches on biointerfaces based on well-defined polymers bearing zwitterionic groups in the side chains. Living radical polymerization provides us excellent interfaces between substrate and biological system included protein solution and blood. Zwitterionic polymer chains effectively reduced protein adsorption. Functionalization by coupling with bioactive molecules on the polymer chains is also summarized from viewpoint of specific molecular recognition.

Tribological Characteristics of Polymer Ultrathin Films Motoyasu KOBAYASHI and Atsushi TAKAHARA
<Abstract>The molecular films have been known as boundary lubricants for a long time. Macro and nanotribological properties of ultrathin films have much attention due to the applications to medical devices, magnetic storage devices, and micro- electromechanical systems. We introduce here tribological properties of the organosilane monolayers prepared by chemical vapor adsorption method, and of densely grafted polymer brushes fabricated by “grafting-from” method based on surface-initiated controlled radical polymerization. This paper reviews the macroscopic frictional properties of well-defined high-density polymer brushes under various testing conditions, and compared these with organosilane monolayers.
