我们报告说，溶液处理的石墨烯层减少了空气中滑动钢表面的摩擦和磨损（相对湿度，30%）。在滑动钢表面的测试中，少量含石墨烯的乙醇溶液将磨损降低了近4个数量级，摩擦系数降低了6倍。对这些结果的一个可能的解释是，石墨烯层作为一种二维纳米材料，并在滑动接触界面上形成保形保护涂层，这些因素有助于剪切和减缓摩擦腐蚀，从而大大减少磨损。(C)2012爱思唯尔有限公司保留所有权利。
We report that solution-processed graphene layers reduce friction and wear on sliding steel surfaces in air (relative humidity, 30%). In tests with sliding steel surfaces, small amounts of graphene-containing ethanol solution decreased wear by almost 4 orders of magnitude and friction coefficients by a factor of 6. A possible explanation for these results is that the graphene layers act as a two-dimensional nanomaterial and form a conformal protective coating on the sliding contact interfaces, and these factors facilitate shear and slow down the tribo-corrosion, thus drastically reducing the wear.
