Bridging interaction between a water drop stabilised by solid particles and a planar oil/water interface.
We demonstrate that the particle mediated interaction between a pendant water drop, covered by a latex particle monolayer, and a planar decane/water interface leads to bridging, analogous to flocculation in solid-stabilised emulsions. The results also provide information about the particle contact angle at the oil/water interface.
