Abstract

This method includes the provision of a first fluid (36) including the first phase and a first precursor polymer of the coacervate contained in the first phase, and the formation of drops of the first fluid (36) in a second fluid (40) intended to form the second phase (16). It includes the steps of introducing a second precursor polymer of the coacervate into the second fluid (40) and, during the formation of each drop (12), or once each drop (12) has been formed, for generating the coacervate layer by interaction between the first precursor polymer and the second precursor polymer at the interface between the first phase (14) and the second phase (16).
