Adhesion mechanics of van der Waals interfaces: Fundamental nanoscale experiments and simulations to enable flexible functional
Abstract
This project’s goal is to investigate the atomic-scale mechanisms governing the adhesionmechanics of atomically-thin two-dimensional materials through an innovative combination ofexperiments and simulations. These materials, which include molybdenum disulfide (MoS2),boron nitride (BN), and graphene, are also known as van der Waals (vdW) materials since theselayered materials are held together with vdW forces. From this study, a predictive understandingof adhesion and how to control and harness it with these materials will emerge. vdW materials,and heterostructures that combine them (e.g., a sandwiched pair of MoS2 and BN) are leading arevolution in electronic behavior which holds promise for deploying them in flexible, wearable,durable devices. The unprecedented electrical, thermal, optical, mechanical, and tribological(friction, adhesion, and wear) properties that arise from their unique two-dimensionalarchitecture render them as crucial materials for Air Force (AF) applications.
