Deformation of soft particles with controlled elasticity by liquid-liquid interfacial tension

Herein we report the deformation of PDMS-based particles at a liquid-liquid interface at varying degrees of softness. Direct visualization of the particle adsorption to the interface reveals at least five different modes of deformation from the complete spreading of a polymer resin droplet to a non-...

Description
Summary:Herein we report the deformation of PDMS-based particles at a liquid-liquid interface at varying degrees of softness. Direct visualization of the particle adsorption to the interface reveals at least five different modes of deformation from the complete spreading of a polymer resin droplet to a non-deforming, rigid particle. In this study we report the deformation of PDMS-based particles at a liquid-liquid interface under complete wetting conditions. By controlling the particle softness, we identified five deformation regimes.
