Abstract

L'invention porte sur un matériau constitué de sphères de carbone creuses, sur son procédé de production et sur une cigarette le contenant. Le matériau constitué de sphères de carbone creuses est produit par le procédé suivant, qui comprend : l'introduction d'un composé organique polyhydrique qui sert de source de carbone et de NaN3 en tant que catalyseur dans un autoclave en une certaine proportion; la fermeture hermétique de l'autoclave et le placement de celui-ci dans un four à haute température; l'élévation de la température du four de la température ambiante à 400 ~ 420°C en 40 min, puis le maintien de la température pendant 350 ~ 450 min; et ensuite le refroidissement, la collecte, le lavage, la filtration et le séchage pour obtenir le matériau constitué de sphères de carbone creuses. La distribution du diamètre des sphères du matériau constitué de sphères de carbone creuses ainsi obtenu se situe entre 100 à 300 nm principalement et l'épaisseur de l'enveloppe de la sphère de carbone creuse est d'environ 20 nm. Le degré de graphitisation du matériau constitué de sphères de carbone creuses obtenu est faible et la stabilité thermique s'avéra bonne par analyse thermogravimétrique, ce qui garantit sa stabilité dans de l'air à plus de 500°C. Lorsque le matériau constitué de sphères de carbone creuses est utilisé comme couche de filtration dans le bout filtrant d'une cigarette, les teneurs en goudron et en ammoniac peuvent être efficacement diminuées.
