| <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

| 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. Keywords: Tribology / Organosilane Monolayers / Polymer Brush / Ultrathin Film / Friction Coefficient / Wear |
