제목 One-Pot Synthesis of Alkylammonium-Functionalized Mesoporous Silica Hollow Spheres in Water and Films at the Air-Water Interface
초록 This paper reports a one-pot sol-gel approach for the synthesis of the alkylammonium-functionalized mesoporous silica particles with hollow structures and mesoporous silica films via hydrothermal reaction through the self-assembly of N-trimethoxy-silylpropyl-N,N,N-trimethylammonium chloride (TMAPS) and tetraethoxysilane (TEOS) as silica sources, dodecyldimethyl(3-sulfopropyl)ammonium hydroxide (DDAPS) and fluorocarbon anion (ammonium perfluorooctanoate (APFO)) as templates. The alkylammonium-functionalized hollow mesoporous silica particles exhibited a different morphology, mesoporosity and hollow structure according to the different DDAPS/APFO ratios, reaction times and reaction temperatures. On the other hand, alkylammon-ium-functionalized mesoporous silica films were produced at the air-water interface, whereas hollow mesoporous silica spheres were produced with precipitation in the bottom of the reaction bottle. The film thickness was controlled from ca. 208 nm to ca. 398 nm.
