Direct Synthesis of Mesoporous Materials Constructed with Silica-Polymer Composite Frameworks |
| 초록 |
Mesoporous materials have generated considerable interest as a consequence of their high surface areas, unusual stability, processability, well defined pores with narrow size distributions. A wide variety of mesostructured inorganic compositions can be readily synthesized using cationic, anionic and neutral surfactants and amphiphilic block copolymers as the supramolecular templates. The versatility of mesoporous materials can be greatly enhanced by the preparation of materials constructed with organic-inorganic hybrid frameworks. We propose a direct synthesis method to create ordered organic-inorganic mesoporous materials constructed with polymer-silica frameworks. This new procedure involves a one-step synthetic strategy based on the blending of a polymer containing a desired functional group and the silica precursor, before adding the mixture to a template solutions or initiating the silica polymerization. This approach needs neither the use of an expensive organically modified ceramic precursor nor the additional post-synthetic reaction of silanol groups to create a functional group on the wall of mesoporous silica. |
