Characterization of carbon sheets. a Raman spectra of exfoliated products in different solvents, SBS (W), SBS/C (E), and SBS/C (E/W = 2:1) compared with commercial SBS, indicating the generation of amorphous carbon during exfoliation in ethanol-containing solvents. b FTIR spectra of commercial SBS, SBS (W), SBS/C (E) and SBS/C (E/W = 2:1). c XPS analysis of C 1s peaks of SBS/C (E/W = 2:1) and SBS/C (E). d EDS spectrum of the indicated region in (e), indicating the carbon sheets. e TEM image of exfoliated SBS/C composite (E/W = 2:1). Scale bar: 200 nm (e)
