Title (EN) STAR POLYMER NANOSHELLS AND METHODS OF PREPARATION THEREOF
(FR) NANOBILLES DE POLYMÈRE EN ÉTOILE ET LEURS PROCÉDÉS DE PRÉPARATION
Abstract: front page image
(EN)A nanoshell is disclosed, comprising a star polymer occlusion complex comprising i) an amphiphilic unimolecular star polymer having a crosslinked core covalently linked to 6 or more independent polymer arms, and ii) a cargo material occluded in the star polymer; and a shell comprising an inorganic material in contact with a peripheral surface of the star polymer occlusion complex.
(FR)L'invention concerne une nanobille, comprenant un complexe d'occlusion de polymère en étoile comprenant i) un polymère en étoile unimoléculaire amphiphile ayant un noyau réticulé relié de manière covalente à 6 bras polymères indépendants ou plus, et ii) un matériau de charge bloqué dans le polymère en étoile; et une enveloppe comprenant un matériau inorganique en contact avec une surface périphérique du complexe d'occlusion de polymère en étoile.
