Abstract
There has been a growing interest in understanding the stabilization mechanism of particle-armoured emulsion droplets over the last few decades due to their importance in many everyday products. Here, the mechanical properties of clay-armoured emulsion droplets were investigated using laser scanning confocal microscopy with an in situ atomic force microscopy measurement. This combination allows the visualization of droplet shape as a function of applied force. The emulsion droplets were found to be mechanically robust, stable against coalescence during drop collisions and able to recover from large deformations without disintegration. A Hookean constitutive law was used to extract the surfac..
