We study the kinetics of the release of monodisperse water-in-oil-in-water
double emulsions in the regime dominated by coalescence of the internal aqu
eous droplets onto the globule interface. By measuring the rate of release
of adsorbed droplets, we directly determine the average lifetime of the thi
n film that forms between the small internal droplets and the globule surfa
ce. Therefore, the activation energy and the natural frequency of the hole
nucleation process within the adhesive thin liquid films are unambiguously
deduced.
