Outline of R&D Project

Previously, we demonstrated that the concentrated polymer brushes (CPBs) newly synthesized by living radical polymerizations inherently possess unique structure and properties such as high elasticity, ultra-low friction/good lubrication, and excellent bio-compatibility. On the basis of such breakthroughs not only in polymer synthesis but also in polymer physics, this ACCEL project aims at reinforcing such “soft and resilient” properties derived from the CPBs and hence applying them on various slide members of mechanical elements, e.g., sliding bearings and seals, for their prolonged life and energy saving. Our final goal is to develop a novel “Soft and Resilient Tribology (SRT)” system for practical use through industry-academia collaboration.
