对石墨烯作为滑动电接触润滑剂的潜力进行了评估。石墨烯以零星的薄片形式沉积在金衬底上，与氮化钛球滑动，不仅通过减少摩擦(降低2-3倍)和磨损(降低2个数量级)显著改善摩擦学性能，而且更重要的是，无论测试环境如何(即在潮湿和干燥条件下)，在经历数千次滑动的滑动接触处显示出稳定和低的电阻。(C)2014 AIP出版有限责任公司。
Potential for graphene to be used as a lubricant for sliding electrical contacts has been evaluated. Graphene, being deposited as a sporadic flakes on the gold substrate sliding against titanium nitride ball shows not only significant improvement in tribological behavior by reducing both friction (by factor of 2-3) and wear (by 2 orders) but also, even more importantly, demonstrates stable and low electrical resistance at the sliding contacts undergoing thousands of sliding passes regardless of the test environment (i.e., both in humid and dry conditions).
