Large-flake graphene membranes up to 300 microm(2) can be exfoliated from graphite by oleyl amine based on solvothermal conditions. The exfoliated graphene sheets are of high quality and have few defects. The graphene dispersion, predominantly composed of monolayer graphene, had a high concentration of 0.15 mg ml(-1), and can be stabilized against re-aggregation.
通过溶剂热条件，从石墨中可以剥离出高达 300 微米（2）的大鳞片石墨烯膜。剥离出的石墨烯片具有高质量，缺陷少。主要由单层石墨烯组成的石墨烯分散体具有高浓度的 0.15 毫克/毫升（1），并且可以稳定防止再聚集。
