It has been shown that gel particles are able to stabilize the oil-water interface and forming emulsions ( the so called "Pickering emulsions"). It has also been shown that thermo-responsive nanogels have the similiar ability to stabilise emulsion with the unique advantage of reversibilty on demand. However, very little is known about the underlying mechanisms of the emulsion ability of these nanogels. Here we would like to study the structural conformation and adsorption mechanisms of thermoal-responsive nanogels at the oil-water to optimise the design of these new class of emulsion stabilizers.
