No full textWe studied a new kind of W/O emulsions based on a
lyotropic liquid crystal as the aqueous droplet phase. The
cholesteric phase, a solution hydroxypropyl cellulose in water was
dispersed in the continuous oil matrix, paraffin oil or heptane.
We made a specific choice of surfactant in order to impose
director anchoring conditions at the oil-water interface and
orient the liquid crystal inside the droplet. The strong anchoring
conditions resulted in a topological defect inside the droplets of
size above the critical value R*. The defect elastic energy
creates a barrier against droplet coalescence, the effect of
topological size selection. We have studied the orientation of the
director inside the droplets and their size distribution
