Influence of quenching temperature on microstructure. (a) Average pore size for different quenching temperatures in ethylene–glycol–water bath. The error bar corresponds to the SD over the mean pore size in the six images analysed per quenching conditions. The inset displays an illustration of the possible phase diagram with a dashed line at the working concentration, highlighting both L–L and S–L demixing. (b–d) Associated cross-sectional SEM images for fibers quenched at −20, 20 and 60 °C
