Original Abstract Submitted
A filtration membrane including a first layer having a triamine-functionalized polysilicate mesoporous material, a second layer including a polysulfone; and a third layer including a polyester terephthalate is described. An orthosilicate group of the triamine-functionalized polysilicate mesoporous material is bonded to a silicon atom of a silicon-containing triamine to form a triamine-functionalized polysilicate backbone, wherein the silicon-containing triamine and one or more tetramines are covalently crosslinked with terephthaloyl chloride to form a polyamide, and wherein the triamine-functionalized polysilicate mesoporous material has a hierarchical structure of MCM-41. The membrane is adapted for use selected from the use group consisting of oil and water separation, water treatment, desalination, and pharmaceutical filtration.
