Title
(EN) CARBON AND CARBON COMPOSITES WITH HIGHLY ORDERED MESOSIZE PORES
(FR) CARBONE ET COMPOSITES DE CARBONE AVEC DES PORES MÉSOMÉRIQUES HAUTEMENT ORDONNÉS
Abstract
(EN)
Mesoporous carbon and silica containing composites are prepared based on the co-assembly of a suitable surfactant in a liquid medium. When a low molecular weight carbonizable polymer and a silica precursor are added to the surfactant solution, a mixture of distinct phases of the materials is formed after solvent evaporation. A polymer/silica solid composite with highly organized mesopores is obtained after surfactant removal. This product has utility as a catalyst support or gas absorbent. And the polymer-silica composite can be easily converted successively to a mesoporous carbon-silica composite and to a bimodal mesoporous carbon material.

Selon la présente invention des composites contenant du carbone et de la silice mésoporeux sont préparés sur la base du co-assemblage d'un agent tensioactif approprié dans un milieu liquide. Lorsqu'un polymère carbonisable de faible masse moléculaire et un précurseur de silice sont ajoutés à la solution d'agent tensioactif, un mélange de phases distinctes des matériaux est formé après l'évaporation du solvant. Un composite solide polymère-silice avec des mésopores hautement organisés est obtenu après l'élimination de l'agent tensioactif. Ce produit est utile en tant que support de catalyseur ou absorbant de gaz. Et le composite polymère-silice peut être facilement converti successivement en un composite carbone-silice mésoporeux et en un matériau de carbone mésoporeux bimodal.
