Preparation of Surfactant-free Nanoemulsion Using Tandem Acoustic Emulsification and Its Application

Abstract

A new technique for the preparation of a highly stable emulsified aqueous solution containing immiscible monomer droplets with diameters of a few tens of nanometers under surfactant-free conditions using tandem acoustic emulsification is described. Highly conductive transparent polymer films and size-controlled polymer nanoparticles were successfully prepared from such emulsified solutions. In addition, tandem acoustically emulsified solution was also applied to a medium for a phase-transfer catalytic reaction.
