Abstract

On décrit une composition particulaire absorbante à haute efficacité et un procédé de préparation dans lequel un noyau solide constitué d'une charge non colloïdale est sensiblement encapsulé dans une couche de polymère formant un hydrogel. On décrit également des dispositifs absorbants utilisant la composition particulaire absorbante à haute efficacité et des procédés pour réaliser ces dispositifs.
