Top-down methods are convenient preparative methods for nanographenes, although the products consist of graphene fragments with a broad size distribution. We show that a combination of dialysis membranes (50, 25, 15, 8, and 2 kD) can conveniently separate nanographenes into five size distributions. The separated nanographenes can be employed as starting materials for carbon-based functional materials.
自上而下的方法是制备纳米石墨烯的便捷方法,尽管产物由尺寸分布较宽的石墨烯片段组成。我们表明,透析膜(50、25、15、8和2千道尔顿)的组合可以方便地将纳米石墨烯分离成五个尺寸分布。分离出的纳米石墨烯可用作碳基功能材料的起始原料。
