Pickering emulsion is eco-friendly and cheap compared to the case of using surfactants, such that it is applied for various fields such as biosensing, drug delivery. In order to control the physical properties of Pickering emulsion, investigation on understanding the mechanism by which solid particles are irreversibly adsorbed to the interface should be preceded. Previously, we quantitatively studied the interfacial adsorption probability according to the shape of individual particles and the salt concentration. In this case, however, when the individual particles approach the interface, many factors involved in the actual Pickering emulsion production were excluded, such as the influence of the interactions between the particles already present at the interface or the effect of convection caused by the use of a spreading solvent. The current work measures the interfacial adsorption probability depending on the interparticle interactions and wettability of colloidal particles. |
