Abstract (en)

[origin: WO2006086789A2] The use of nanostructured chemicals based on polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) are used to control porosity in organic and inorganic media. The precisely defined nanoscopic dimensions of this class of chemicals enables porosity to be both created (increased) or reduced (decreased) as desired. The thermal and chemical stability of the POSS/POS nanostructures and the ability of these nano- building blocks to be selectively placed or rationally assembled with both inorganic and organic material mediums allow tailoring of porosity.
