Title
(EN) POROUS EPOXY NANOCOMPOSITE MONOLITHS
(FR) MONOLITHES NANOCOMPOSITES ÉPOXY POREUX
Abstract
(EN)
Method of preparing a porous material includes preparing a mixture of from about 10 to about 30% by mass of a matrix material, from about 20 to about 60% by mass of a plurality of particles, from about 20 to about 60% by mass of a porogen, and from about 1 to about 10% by mass of an interfacial compatibilizer. The matrix material and the porogen may be selected so as to be phase separated in the mixture. The method may further include placing the mixture into a form; initiating a solidification of the matrix material during which the porogen remains nonvolatile and the matrix material and the porogen remain phase separated; and removing at least a portion of the porogen to obtain the porous material. Porous materials produced by the methods. Microfluidic channels produced by the methods.

Un procédé de préparation d'un matériau poreux comprend la préparation d'un mélange d'environ 10 à environ 30 % en masse d'un matériau de matrice, d'environ 20 à environ 60 % en masse d'une pluralité de particules, d'environ 20 à environ 60 % en masse d'un porogène, et d'environ 1 à environ 10 % en masse d'un agent de compatibilité interfacial. Le matériau de matrice et le porogène peuvent être sélectionnés de façon à être séparés en phase dans le mélange. Le procédé peut en outre comprendre le placement du mélange dans une forme; l'initiation d'une solidification du matériau de matrice pendant lequel le porogène reste non volatil et le matériau de matrice et le porogène restent séparés en phase; et l'élimination d'au moins une partie du porogène pour obtenir le matériau poreux. L'invention concerne des matériaux poreux produits par les procédés. Des canaux microfluidiques produits par les procédés sont décrits.
