Title (EN) CAPSULES HAVING SURFACTANT TETHERED OUTER SHELLS AND METHODS FOR MAKING SAME
(FR) CAPSULES AYANT DES ENVELOPPES EXTERNES ATTACHÉES À UN AGENT TENSIO-ACTIF ET LEURS PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)Microcapsules are disclosed that have a core composition encapsulated within a polymer wall, and an inorganic shell connected to an exterior surface of the polymer wall by a surfactant. The inorganic shell has a cation attracted to the surfactant and an anion or anion equivalent chemically bonded to the cation to form the shell or has the metal portion of a metal-containing compound attracted to the surfactant to form the shell. The shell may comprise a Ca, Mg, or Ag metal compound. The shell may be a graphene oxide-metal compound.
(FR)L'invention concerne des micro-capsules qui comportent une composition de noyau encapsulée dans une paroi polymère, et une enveloppe inorganique reliée à une surface extérieure de la paroi de polymère par un tensioactif. L'enveloppe inorganique a un cation attiré vers le tensioactif et un anion ou équivalent d'anion chimiquement lié au cation pour former l'enveloppe ou a une partie métallique d'un composé contenant du métal attiré vers l'agent tensio-actif pour former l'enveloppe. L'enveloppe peut comprendre un composé métallique Ca, Mg ou Ag. L'enveloppe peut être un composé de graphène oxyde-métal.
