제목 Synthesis of Various Nanostructured Silica Using Ionic Block Copolymer Templates
초록 Inorganic-organic hybrid materials have potential applications in functional materials and smart systems. We have investigated the various morphologies of silica structure via sol-gel reaction using the ionic block copolymer and the silica source under acidic condition. The ionic block copolymer is formed micelle in ionic block selective solvents. The nanostructured silica is synthesized via ion pair interaction between charged block templates and silica precursors. We can control hollow or mesoporous silica structures by changing the concentration and the degree of protonation. These parameters can control the interaction between templates and matrix and the mobility of inorganic-organic hybrid complex. After calcination, these nanostructures could be analyzed using transmission electron microscopy (TEM), field emission-scanning electron microscopy (FE-SEM) and small angle x-ray scattering (SAXS) methods.
