Figure 2

Representative evaporation-controlled DoS capillary thinning measurements of 3 mg/mL PEO in: (a) water, (b) NMF, (c) DCM, and (d) chloroform. Insets in (b) and (d) show 2D images of the thinning inside of the chamber at (from L to R) \(R/R^{*}= 1\) (onset of EC regime), 0.7, 0.4 and 0.1. (a,b) As expected, no statistically significant difference in \(\lambda _{E}\) is observed for low volatility solvents (water, NMF); see Table 1. (c,d) In more volatile solvents (chloroform, DCM), pronounced differences in the thinning profiles and \(\lambda _{E}\) result between trials taken inside versus outside the environmental control chamber
