Multiple Emulsions Controlled by Stimuli-Responsive Polymers

The phase inversion of water‐toluene emulsions stabilized with a single thermo‐ and pH‐sensitive copolymer occurs through the formation of multiple emulsions. At low pH and ambient temperature, oil in water emulsions are formed which transform into highly stable multiple emulsions at pHs immediately...

Description
Summary:The phase inversion of water‐toluene emulsions stabilized with a single thermo‐ and pH‐sensitive copolymer occurs through the formation of multiple emulsions. At low pH and ambient temperature, oil in water emulsions are formed which transform into highly stable multiple emulsions at pHs immediately lower than the inversion border. At higher pHs, the emulsion turns into a water in oil one.
