介绍了一种利用超声波清洗器从膨胀石墨中合成氧化石墨烯的简单方法。由于插层（氧化）和超声波处理之间的协同效应，该方法显示出比Hummers的方法大大降低的酸需求、节省时间/更少的能量消耗、高生产率和没有有毒气体的释放。在小于1小时内获得了层间距为100 nm的单层GO。该工艺安全可靠，有望用于GO的规模化生产。氧化石墨烯膜和还原氧化石墨烯（rGO）膜都显示出良好的弯曲柔性。
A simple method for the synthesis of graphene oxide (GO) from expanded graphite using an ultrasonic cleaner is described. Due to the synergistic effect between intercalation (oxidation) and ultrasonication, this method showed strongly decreased demand for acid, time saving/less energy consuming, high productivity and without the release of toxic gas(es) than Hummers’ method. Single sheets of GO with layer spacing of ∼1 nm were obtained in less than 1 h. This procedure was safe and expected to be applicable for the scale production of GO. Both graphene oxide film and reduced graphene oxide (rGO) film showed good bending flexibility.
