제목 Synthesis Route of Mesostructured Material using the Self-Assembly of Surfactants and the Layered Sodium Silicate Minerals
초록 Layered silicic acids, which are easily derived from layered silicates such as ilerite(Na2Si8O17•nH2O), magadiite(Na2Si14O29•nH2O), kenyaite (Na2Si22O45•nH2O) and kanemite (NaHSi2O5•3H2O) by proton exchange, are found to be very useful hosts in the formation of pillared materials because of the presence of reactive silanol groups on their interlayer surfaces. Recently, the MCM-41/-48 transformation was performed by driving the transformation of layered sodium silicate minerals by altering surfactant packing within the micellar surfactant templates. However, many researches about meso-structured materials by the surfactant-templated sol-gel method have not yet been illustrated for the structure formation process.
In this study, we suggest about the synthesis route how to derive meso-structured materials from layered sodium silicate minerals using Surfactants containing a hydrophilic head group and a long hydrophobic tail group within the same molecule and will self-organize in such a way as to minimize contact between the incompatible ends.
