Hybrids and Composites

In a similar spirit, but without any consideration about covalent cross-linking, dry nanostructured silicas have been also used for the synthesis of some sifica/polyurethane composites [48]. Silica nanopowders (e.g., finely divided silicas with characteristic dimensions between 10 nm and 100 pm) have been dispersed in various polyurethane sols. After gelation in the presence of these inorganic fillers, the polyurethane-based composites can be considered as superinsulating materials with thermal conductivities lower than 0.020 W/m K. [Pg.201]

The surface properties of CNTs are paramount for their hybridization with other components. The formation of large bundles due to van der Waals interactions between hydrophobic CNT walls further limits the accessibility of individual tubes. Functionalization of CNTs can enhance their dispersion in aqueous solvent mixtures and provide a means for tailoring the interfacial interactions in hybrid and composite materials. Functionalization techniques can be divided in covalent and non-covalent routes, which will be described in greater detail in Chapter 3. [Pg.18]

The type of chemical system that templates can be used for is virtually limitless. Templates have been used for the preparation of pnrely organic materials, ceramic materials, and all other kinds of hybrid and composite systems in between from metallo-organic and coordination systems to polymers. In addition, the phase in which the templates act is extremely varied, from the solntion-state syntheses of molecnles to the growth of layers on crystals and the nse of soft materials for the formation of porons... [Pg.1349]
