Abstract
Co-micelle emulsion templating (co-MET) technique is a new method to synthesize uniform and ordered porous silica from tetraethylortosilicate precursor using double polymer as templates. In this study, co-MET technique was conducted by varying template type (namely PEG/acrylamide and 2(acryloyloxy)N,N,Ntrimethylethanaminium chloride/acrylamide) and percentage of polymer (2.5%, 5%, 10%, 15% and 20% for PEG and 0.5%, 1%, 2.5%, 5%, 10% for 2(acryloyloxy)N,N,Ntrimethylethanaminium chloride). The resulting porous silica were then characterized by SEM-EDS, BET and XRD to investigates the pore character and structure of silica. Based on SEM-EDS and BET analysis, it is shown that the amount and the type of polymer gave a significant effect to the structure formation of the porous silica. Cationic polymer as templates gave higher surface area and uniform pore size than neutral polymer templates. Polymer concentration of 2.5% gave the best result for both template types, resulting an interconnected mesopore silica with surface area of 615 m2/g for PEG and 1137 m2/g for 2(acryloyloxy)N,N,Ntrimethylethanaminium chloride.
