低成本、高产量地生产石墨烯纳米片(GNS)对于实际应用是必不可少的。在干冰存在下，通过对原始石墨进行简单的球磨，我们获得了高得率的边缘选择性羧化石墨(CG)。生成的ECG在各种溶剂中高度分散，可自我剥离成单层和少数层(
Low-cost, high-yield production of graphene nanosheets (GNs) is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to self-exfoliate into single-and few-layer (
