Covalent grafting of polyacrylamide onto mesoporous MCM-41 silica via free radical polymerization

Autor: H. Iván Meléndez-Ortiz, E.M. Saucedo-Salazar, Bertha Puente-Urbina, Griselda Castruita-de León, Carlos Gallardo-Vega

Publikováno v: Journal of Porous Materials. 24:1527-1533

MCM-41 mesoporous silicas were covalently modified with polyacrylamide (PAAm) by a novel grafting strategy. The effect of various parameters such as monomer concentration, reaction time, and temperature on the content of PAAm onto MCM-41 silicas were
