Table S1: Hansen and Hildebrand parameters and graphene dispersibilities for all solvents studied.
11
Note in all cases except those marked by *, the Hansen and Hildebrand parameters were taken from
12
the database in HSPiP software. In general, this data is also available in Hansen, C. M., Hansen
13
Solubility Parameters - A User's Handbook. CRC Press: 2007.
14
* Hansen parameters calculated using algorithms provided in HSPiP software. Y-MB algorithm was
15
used to calculate δD, the Stefanis-Panayiotou algorithm was used to calculate δH while the average
16
of the Y-MB and Stefanis-Panayiotou results was taken as δD. For justification, see Bergin, S. D.;
