Highly clear and transparent nanoemulsion preparation under surfactant-free conditions using tandem acoustic emulsification.

A new technique for the preparation of a highly clear and transparent emulsified aqueous solution containing immiscible monomer droplets with diameters of a few tens of nanometres under surfactant-free conditions using tandem acoustic emulsification is described. Highly conductive transparent polymer films were successfully prepared from such an emulsified solution. © The Royal Society of Chemistry 2011
