Chemistry of inorganic building blocks
The possibilities of silica-, silicate-, and siloxane-based building blocks for the design of nanomaterials and nanocomposites will be presented. The properties of modified 2D silicate sheets are controlled by the introduction of functional groups. Organic modification of interlayer surfaces by silylation provides various possibilities including exfoliation to nanosheets. Layered silicates can also be regarded as 2D building blocks which can be converted to three dimensional networks by interlayer condensation or by using cross linking agents. Nanosized silica- and siloxane-based components, such as mesoporous silica nanoparticles (MSN) and dendritic siloxane oligomers should also have high potentiality because the surfaces can be modified in various ways to adapt the conditions required for various applications. Because mesoporous materials are compositionally, structurally, and morphologically tuned, there are many potential applications in various fields including separation, catalysis, nanocomposite formation, medicine, electronics, optics, etc.
