Figure 5.

The plot shows the relationship between the aspect ratio [A/R, defined as the maximum length parallel to the tail (A) over the maximum length perpendicular to the tail (R)] of the tailed microgels and the glycerol concentration in the gelation bath. The microgels were prepared from an aqueous 1.5 wt. % SA solution with a flow rate of 1800/30 (O/W) μl h⁻¹; in gelation bath, the upper oil layer consisting of n-decanol dispersed with 5 wt. % span 80 while the aqueous bottom layer consists of an aqueous solution containing 15 wt. % Ba(Ac)₂ and varying glycerol concentration. The insets are the representative optical microscopy images for the selected points. Error bars represent the standard deviation.
