Nanomechanical and tribological characterization of the MPC phospholipid polymer photografted onto rough polyethylene implants

► p(MPC) brushes were photografted on rough surface of UHMWPE joint implants. ► p(MPC) thickness and mechanical properties are characterized by AFM-nanoindentation. ► p(MPC) tribological proprieties are characterized using a homemade biotribometer. ► Grafted p(MPC) layers cover and smooth the UHMWPE surface and prevent wear.
