Abstract

La présente invention concerne un filtre à particules comprenant au moins un hydrogel formé en solution aqueuse à une température inférieure à O °C. Le filtre peut arrêter des particules de fumée par physisorption à la surface solide du gel ou par chimisorption si le gel est fonctionnalisé de façon appropriée. L'efficacité du filtre à arrêter les particules solides et la chute de pression peuvent être contrôlées en faisant varier la porosité et la distribution de la taille des pores du filtre qui peuvent à leur tour être modulées en faisant varier le rapport entre le monomère et l'eau et le rapport entre le monomère et l'agent de réticulation dans la solution de prépolymère. Le filtre peut réduire la teneur en particules de la fumée. L'invention concerne également une cigarette comprenant au moins un filtre à particules selon l'invention ainsi qu'un procédé de filtration de la fumée.
