Interfacial rheology – measuring mechanical properties of complex-liquid interfaces
In this presentation, I will introduce colloidal, micron-sized particles at liquid interfaces. These are interesting 2D model systems, but they are also interesting for (potential) applications e.g. particle-stabilized aka Pickering emulsions and bijels (bicontinuous Pickering emulsions). The mechanical properties of the particle-laden interfaces are challenging to measure, but they are important, for example to explain Pickering-emulsion stability. I will summarize some of our past and recent work on measuring and interpreting the mechanical properties of particle-laden liquid interfaces, including our recent development of ‘contactless’ interfacial rheology.
Today at 4:00 pm, back in JCMB room 2511.
