Abstract
Facile exfoliation of graphite: High-quality graphene sheets are produced directly from graphite by a facile chemical approach. The new strategy for non-oxidized chemical exfoliation of graphite is based on a pre-intercalated process with oleum and a further strong reaction with sodium in the graphite layers under grinding conditions. This method is facile, low cost, and high throughput.
摘要
石墨的简易剥离
通过一种简单的化学方法，直接从石墨中制备出高质量的石墨烯片。这种新的非氧化化学剥离石墨的策略基于一个预插层过程，使用发烟硫酸，然后在研磨条件下，石墨层与钠发生进一步的强反应。该方法简便、成本低、产量高。
