Description
Hikaru Okubo, Daiki Kagiwata, Ken Nakano, and Yoshinobu Tsujii probe wear in dense polymer brushes in 2023. Such brushes, far denser than normal ones, give very low friction. How their layered build drives that slickness and its wear was not fully clear.
Light and force tools tracked the gap and stiffness where a steel ball met the coated glass in liquid. Pressing tests confirmed three layers: dilute, middle, and dense. Sliding wore the brush thinner, yet the dilute top layer kept its thickness. Wear thus proceeds while a fresh soft layer keeps forming at the surface.
