Description

One highly used route to high throughput solution-based synthesis of graphene is the oxidation/intercalation of the bulk graphite followed by layer separations, with a resulting highly oxidized graphene, and then a reduction to graphene. The required oxidation state generally induces a large number of structural defects in the final graphene. Here we report a scalable H2SO4 intercalation driven synthesis method for graphite intercalated compound (GIC), followed by energetic exfoliation via microwave exposure at ambient conditions that produces with high efficiency and throughput a material consisting of a few layers graphene sheets.
The 2D morphological surface characterization has been done by SEM analysis, the film chemical composition has been identified by EDS and XPS techniques and the graphene layer plus its lateral dimension have been determined using AFM analysis based on its topographic height images.
