The Role of Two-Dimensional Materials in Superlubricity on Friction and Wear-Prone Surfaces

Abstract

Moving mechanical systems create a lot of friction; therefore, a lot of the energy produced is used to overcome it. It is vital to find unique ways to develop lubricants that allow for more effective control or decrease friction to reach a sustainable future. High friction, if not efficiently reduced or controlled, can result in higher wear losses and, as a result, shorter system life and lower reliability. Two-dimensional (2D) materials have distinct friction and wear properties from their three-dimensional (3D) counterparts. They can be used as additives in oils and composites to reduce stiction, friction, and wear, even though they are ultra-thin even with numerous layers. The role of these materials in superlubricity on surfaces prone to friction and wear is discussed in this chapter. These materials are solid two-dimensional lubricants that can address developing needs in mechanical systems in motion in current and emergent real-world applications.
