Emulsions stabilized by forming a polymeric thin film at the interfaces of oil phase and water phase

摘要

The present invention relates to a stabilized emulsion to form a polymer thin film produced by the oil / water interface using the amphiphilic polymer. More specifically, the emulsion is 1) oil phase, 2) an aqueous solution phase, and 3) as a distributed system consisting of amphiphilic polymers, in particular by using the amphiphilic polymer has a poly has a caprolactone to a hydrophobic block of polyethylene glycol as a hydrophilic block characterized in that the forming the polymer thin film at the interface of the emulsion. These amphiphilic polymers can have a characteristic having a new mechanism for stabilizing the interface while the hydrophobic block form a solidified polymer film does not dissolve in the oil phase is distributed in the interface. ; Amphiphilic polymers, block copolymers, emulsion, polycaprolactone, polyethylene glycol, a polymer thin film
