我们提出了一种完全绿色的方法，通过紫外线照射还原脱落的氧化石墨烯（GO）来合成和稳定水性石墨烯分散体。聚乙烯醇吡咯烷酮（PVP）通过一步功能化来提高还原氧化石墨烯（RGO）的分散性。该方法成本低、操作简单，无需使用任何光催化剂或还原剂，为大规模生产中绿色制备稳定的RGO分散体开辟了新的可能性。
We present a totally green approach towards the synthesis and stabilization of aqueous graphene dispersions through UV-irradiated reduction of exfoliated graphene oxide (GO). Polyvinyl pyrrolidone (PVP) is used to enhance the dispersibility of reduced graphene oxide (RGO) by one-step functionalization. The proposed method is low cost and easy without using any photocatalysts or reducing agents, which can open up a new possibility for green preparation of stable RGO dispersions in large-scale production.
