Abstract:
We prezent a theoretical and experimental study of amphiphilic particles:these are small solid spheres treated so that one part of solid is hydrophilic whereas the other is hydrophobic.These beads have a specific behaviour at the inteface between two fluids of different polarities since they are anchored at the interface along the border between the two parts,in a large range of values for ratio between the areas of the hydrophilic and hydrophobic sides.
