Abstract
Mesoporous silica containing a large amount of aminopropyl groups has been successfully synthesized via the anionic templating route. The electrostatic interaction between the positively charged amino groups in 3-aminopropyltriethoxysilane and the negatively charged sulfate head groups in sodium dodecyl sulfate is a driving force for the self-assembly of silica−micelle composite.
