Self-supporting films of clay minerals and metal oxides: Molecular ceramics


  • This research was conducted as part of the Molecular Architecture Project operated by the Research Development Corporation of Japan.


Self-supporting, flexible films of montmorillonite that retain the fundamental characteristics of the mineral have been produced (The Figure shows a cross-sectional view). This demonstrates that one practical disadvantage of clay minerals-that they are usually only available as powders-can be overcome. Further examples of the extension of microscopic layer structures to the macroscopic scale to produce “molecularly defined ceramics” are presented.
