Graphite-to-Graphene: Total Conversion Academic Article uri icon

abstract

  • We examined diluents with an increasing conjugation degree and hence improved ability to form a planar conformation covering the surface of the graphitic materials. We started from non-aromatic compounds (eg, NaCl) and non-conjugated aromatics (eg, polystyrene), and proceeded through semiconjugated aromatics (eg, dibenzo crown ether and diphenylbutadiyne) to fully conjugated aromatics (eg, naphthalene, anthracene, and pyrene)(Figure 2). The more conjugated (and planar) the diluent, the stronger its adsorption to and protection of the graphitic surface from converting to amorphous carbon, as analyzed by thermogravimetric analysis (TGA)[20](Figure 2b, and Section S3. 1, Supporting Information). TGA parameters, such as T1/2, the temperature of the combustion step at which half of the total weight loss is reached (Section S3. 1, Supporting Information), is …
