Templating of Nonionic-Surfactant Phases

All the mesoporous ceramic oxides obtained by this method are amorphous on the atomic level, but show periodicities on the nanometer length scale and narrow pore size distribution. The outcome of the process is very predictable, as the binary phase diagram of the surfactant can be used as a guideline towards the nanostructure design. The transmission electron microscopy images of siH-cas derived from three different LLC surfactant phases are shown in Fig. 3. 

It is worth mentioning that the oligo(ethylene oxide) headgroups of the nonionic surfactants are firmly anchored in the solidifying inorganic matrix. There-
