TI  - Synthesis of thermally stable highly ordered nanoporous tin oxide thin films with 
      a 3D face-centered orthorhombic nanostructure.
PG  - 10538-41
AB  - Thin films of nanoporous tin oxide with a 3D face-centered orthorhombic 
      nanostructure have been synthesized by self-assembly that is controlled by 
      post-coating thermal treatment under controlled humidity. In contrast to the 
      conventional evaporation-induced self-assembly (EISA), the films here have no 
      ordered nanostructure after dip-coating. However, the initial coatings are formed 
      under conditions that inhibit significant hydrolysis and condensation for 
      extended periods. This allows the use of postsynthesis thermal vapor treatments 
      to completely control the formation of the nanostructure. With EO106-PO70-EO106 
      (Pluronic F127) triblock copolymer as the template, highly ordered nanostructures 
      were generated by exposing the disordered films to a stream of water vapor at 
      elevated temperature, which rehydrates the films and allows the formation of the 
      thermodynamically favored phase. Further exposure to water vapor drives the 
      condensation reaction through the elimination of HCl. The X-ray diffraction 
      pattern from the nanostructure was indexed in the space group Fmmm as determined 
      by analysis of 2D small-angle X-ray scattering patterns at various angles of 
      incidence. The nanostructure is then stabilized and made nanoporous by extended 
      controlled thermal treatments. After self-assembly and template removal, the 
      films are thermally stable up to 600 degrees C and retain an ordered, 
      face-centered orthorhombic nanostructure.
