Motoyasu KOBAYASHI and Atsushi TAKAHARA
<要旨>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.
