Researchers dynamically tune friction in graphene

"very low friction turned on using external electric fields that modulate lubricant properties and material surfaces as well as interactions between them... 2D materials high mechanical strength and chemical and thermal stability... reducing energy consumption in nano- and micro-electromechanical systems, in addition to allowing dynamic control of friction while mitigating enhanced wear and corrosion of sliding surfaces when direct bias applied"
