Abstract

A method for producing an amphiphilic particle or an anisotropic particle includes combining seed particles with a monomer emulsion to obtain monomer-swollen seed particles, polymerizing the monomer-swollen seed particles to obtain polymerized monomer-swollen particles, and hydrolyzing the polymerized monomer-swollen particles. An amphiphilic particle is adapted to stabilize a first type of multiphasic mixture comprising a first aqueous phase having a first pH and a second type of multiphasic mixture comprising a second aqueous phase having a second pH.

Claims (4)

1. A biphasic amphiphilic particle adapted to stabilize a first multiphasic mixture comprising a first aqueous phase having a first pH and a second multiphasic mixture comprising a second aqueous phase having a second pH.

2. The biphasic amphiphilic particle of claim 1 , adapted to cause a phase inversion of the first multiphasic mixture into the second multiphasic mixture by adjusting the first pH of the first aqueous phase to the second pH.

3. The biphasic amphiphilic particle of claim 1 , wherein the first multiphasic mixture is a water in oil emulsion and the second multiphasic mixture is an oil in water emulsion.

4. The biphasic amphiphilic particle of claim 1 , the particle being adapted to cause a phase inversion of an emulsion.
