Supramolecular repair of hydration lubrication surfaces

Supramolecular repair of hydration lubrication surfacesWe propose the use of selective host-guest interactions to assemble lubricating polymers on functionalized surfaces.The concept is demonstrated using a cyclodextrin-terminated lubricating polymer that associates with an adamantanefunctionalized surfaces.Areas of the surface that are damaged by mechanical wear are repaired as more lubricating polymer self-assembles with the surface.Lowfriction surfaces that can be easily repaired are needed to limit energy losses and damage in biomedical and mechanical devices.
