10. 11 We, however, do find significant adsorption of PS from chloroform onto silica, indicating marginally favorable energetics, which may contribute to the low coverages observed.

15. Toluene and methanol are displacers according to ref 11. Although we did not measure significant desorption into the quiescent supernatant for either of these solvents on the time scales of observation, PS does desorb from silica on longer time scales under agitation, consistent with ref 11.
