Figure 5

Ellipsometrically derived changes in LCST (relative to no salt; LCST = 29.3 °C) of the 714 Å PNIPAM brush in electrolytes composed of 0.2 and 0.9 mol % KSCN, LiI, LiBr, and KCl in a 6 mol % DMSO solvent composition. Top x-axis identifies the probed anions and the lower their respective þ values. Square symbols represent a Li+ counter-cation and circle symbols represent a K+ counter-cation. Corresponding changes in brush thickness as a function of temperature are presented in Figure S2.5. Uncertainty is smaller than the data point.
