a Specific viscosity of SEBS/toluene solution as a function of the concentration of SEBS in the solution. b Flow curve of 5, 15, and 25 wt.% SEBS solutions (c) Frequency sweep of 25 wt.% SEBS solution before and after solidification by solvent exchange. d Illustration showing the setup for the in situ monitoring storage modulus under ethanol exposure. e Apparent storage modulus changes of 5, 15, and 25 wt.% SEBS solutions under ethanol exposure. f Thickness inference of the solid SEBS polymer after ethanol exposure (g) Photograph demonstrating the yield stress of the bath media. h Steady shear data of different bath mediums (i) Break-up timescale as a function of diameter for 25 wt.% SEBS, 15 wt.% SEBS with X = 0.7127 for Newtonian viscous filament. The horizontal lines show the time required to develop a thickness based on elasto-capillary length scale.
