| Outline of Final Research Achievements |
Development of low frictional materials are important issue to shift from mass consumption society to circular one because 75% of the degradation or breakdown are related to friction and wear of contact surface. In this research, we pursued improving the robustness of concentrated polymer brushes (CPB) by supplying brush resources from inside of lubrication layer to form loop-shaped CPB by self-aggregation.
Applying ABA-type triblock coplymer PBMA-PEG-PBMA into PBMA as loop-shaped CPB resources effectively reduced friction and improved robustness in glycerol solution. This concept was also confirmed in ionic liquids system, which means that it is expected to be applied for high temperature or vacuum.
