In this paper, we demonstrated a simple and cost-effective method to produce graphene from graphite in ethanol using ultrasound assisted with curcumin. The influence of curcumin concentration, starting graphite amount, sonication power, and sonication time on the graphene concentration was studied schematically. The π-π interaction between curcumin and graphene, being confirmed by FTIR spectrum, facilitate the exfoliation of the graphite into graphene. The concentration of the graphene in the ethanol reached up to 1.44 mgmL^-1 and the exfoliated suspension was relatively stable. The content of monolayer, bilayer, and multilayer in the exfoliated graphene suspension were 21%, 37%, and 42%, respectively. The as-prepared graphene sheets were free-defect. This novel approach may not only enable to exfoliate the graphite into graphene but also to make the graphene-curcumin hybrid which might find applications in pharmaceutical industry.

在本文中，我们演示了一种简单而经济高效的方法，该方法使用超声波辅助姜黄素，由乙醇中的石墨生产石墨烯。简要研究了姜黄素浓度，起始石墨量，超声处理能力和超声处理时间对石墨烯浓度的影响。姜黄素和石墨烯之间的π-π相互作用已通过FTIR光谱证实，有助于石墨剥落成石墨烯。乙醇中石墨烯的浓度高达1.44 mgmL ^-1剥落的悬浮液相对稳定。片状石墨烯悬浮液中单层，双层和多层的含量分别为21％，37％和42％。所制备的石墨烯片是自由缺陷的。这种新颖的方法不仅可以将石墨剥落成石墨烯，而且可以使石墨烯-姜黄素杂化体在制药工业中得到应用。
