✦ Synopsis
Analysis: The size and the polydispersity of the liquid-crystalline colloids were determined by dynamic light scattering at a fixed scattering angle of 90 using a zetasizer 3000 HSA (Malvern Instruments).
A scanning electron microscope 1530 Gemini' (LEO) was used for the scanning electron microscopy (SEM) imaging. TEM investigations were performed using an FEI TECNAI F30 ST equipped with a field-emission gun at 300 kV. The samples were prepared directly on a carbon-coated copper grid, subsequently dried, and were investigated at room temperature. Alternatively, for cryo-TEM investigations the aqueous dispersions were plotted in liquid propane and investigated at approximately ±160 C using a GATAN single-tilt cryotransfer sample holder.
