(FR) MOUSSES POLYMÈRES COMPRENANT DES NANOTUBES DE CARBONE FONCTIONNALISÉS
Abstract
(EN)
This disclosure describes micro, sub-micro, and nano-cellular polymer foams formed from a polymer composition that includes a polymer and functionalized carbon nanotubes, and systems and methods of formation thereof. The microcellular polymer foam has an average pore size within a range of 1 micron to 100 microns, the sub-microcellular polymer foam has an average pore size within a range of 0.5 microns to 1 micron, and the nano-cellular polymer foam has an average pore size within a range of 10 nanometers to 500 nanometers. In other aspects, this disclosure describes micro, sub-micro, and nano-cellular polymer foams formed from a polymer composition that includes a polymer and non-functionalized carbon nanotubes.

La présente invention concerne des mousses polymères micro-, sous-micro- et nano-cellulaires formées à partir d'une composition polymère qui comprend un polymère et des nanotubes de carbone fonctionnalisés, ainsi que des systèmes et des procédés de formation de celles-ci. La mousse polymère micro-cellulaire présente une taille de pores moyenne se situant dans la plage de 1 à 100 microns, la mousse polymère sous-micro-cellulaire présente une taille de pores moyenne se situant dans la plage de 0,5 à 1 micron, et la mousse polymère nano-cellulaire présente une taille de pores moyenne se situant dans la plage de 10 à 500 nanomètres. Selon d'autres aspects, la présente invention concerne des mousses polymères micro-, sous-micro- et nano-cellulaires formées à partir d'une composition polymère qui comprend un polymère et des nanotubes de carbone non fonctionnalisés.
