▎ 摘　　要

A novel interface-facilitated synthesis of graphene-like carbon nanosheets from P123 is reported. The morphology and structure of the carbon nanosheets were characterized though FESEM, TEM, AFM, XRD, Raman and FTIR. The formation mechanism of the graphene-like carbon nanosheets is proposed. P123 serves a dual function of structure-directing agent and carbon precursor, which first assembles at the toluene-HCl interface and then is in situ carbonized to carbon nanosheets. This process shows several advantages such as mild condition, simple procedure and low cost In addition, the obtained carbon nanosheets can be effectively confined at the interface and self-organize into film with high uniformity.
