Effect of Polyethylenimine Loading on the Physicochemical Properties of Amine-Functionalized Si-MCM-41

Si-MCM-41 with highly ordered uniform mesopores was synthesized hydrothermally at 100 oC. The calcined Si-MCM-41 was then functionalized with 10-50% (w/w) polyethylenimine (PEI) via impregnation method. The physicochemical properties of these samples were characterized using FTIR, TGA, FESEM, TEM an...
