“…MXenes, a new member of two-dimensional (2D) material family, has shown promise in reducing friction and wear due to their layered structure of transition metal carbides. 10–13 So far, MXenes have caught considerable attention in the fields of energy storage, 14–18 polymer, 19 environments, 20,21 and thermal management. 22,23 Previous studies showed that adding limited amount of MXene to base oils such as polyalphaolefin (PAO) and silicon oil can reduce the coefficient of friction.…”
