METHOD FOR THE MANUFACTURE OF CORE-MEMBRANE CAPSULES, BY INTERFACIAL POLYMERIZATION

A method for the manufacture of core-membrane capsules, which manufacturing method includes: (i) a step of providing two immiscible solutions, namely: a first solution containing at least one first reactive molecule including at least two azlactone groups, and a second solution containing at least o...

Zusammenfassung:	A method for the manufacture of core-membrane capsules, which manufacturing method includes: (i) a step of providing two immiscible solutions, namely: a first solution containing at least one first reactive molecule including at least two azlactone groups, and a second solution containing at least one second reactive molecule including at least two amine groups, and (ii) an interfacial polymerization step during which the immiscible solutions are mixed so that the reactive molecules react together by an interfacial polymerization reaction, on the surface of the droplets, to form the membrane including a polyamide polymer.
