Figure 5.

Microstructure of starting systems (left column) and physical properties of the obtained films (right column). Laser scanning confocal microscopy images of emulsions used to prepare films: (A) conventional emulsion; (B) nanoemulsion. Physical properties: (C) total color change due to addition of TiO₂ or to changes in droplets size (conventional to nano); (D) storage modulus (E’), Young modulus (E), and elongation at break (ε_b). Blue: film from conventional emulsion; red: film from nanoemulsion (reprinted from ref. [152,155,160]).
