  • Hydrocapsules and method of preparation thereof
    Patent number: 6780507
    Abstract: A method is described for the formation of microcapsules which contain a liquid composition in the core, which is surrounded by a polymeric shell, membrane, or coating. The microcapsules are produced by simultaneously extruding the liquid core material along with a polymerizable liquid through concentrically-aligned nozzles to form spherically-layered biliquid droplets, followed by energy input in the form of heat or light which causes polymerization of the outer layer. The capsules formed by this method are capable of containing a variety of liquid materials having a composition ranging from completely aqueous to completely non-aqueous.
