Abstract
The present invention provides a process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner. A dispersion phase is ejected from a dispersion phase-feeding port toward a continuous phase flowing in a microchannel in such a manner that flows of the dispersion phase and the continuous phase cross each other, thereby obtaining microdroplets, formed by the shear force of the continuous phase, having a size smaller than the width of the channel for feeding the dispersion phase.
Claims3
An apparatus for producing an emulsion, comprising:
- (a) a substrate having parallel electrodes;
- and
- (b) a microchannel disposed on the substrate,
- (c) wherein a dispersion phase disposed at the upstream side of the microchannel is attracted and then ejected by a moving electric field, applied to the parallel electrodes, to form the emulsion.
