Figure 2

POM images of P‐E7PBA in a) aqueous medium under bright field and in b) aqueous medium and c) MEM, under cross‐polarization. d) P‐E7 in aqueous medium under cross‐polarization. The inset images are not to scale. The scale bars are 10 µm. P‐E7PBA: E7 doped with PBA and encapsulated in the polymeric microcapsule. P‐E7: E7 without PBA, encapsulated in the polymeric microcapsule.
