Hydrophobic Silsesquioxane Nanoparticles and Nanocomposite Surfaces (POSTPRINT)

Fluorinated Polyhedral Oligomeric Silsesquioxanes are hydrophobic nanoparticles. One compound, FD8T8, is ultrahydrophobic, possessing a water contact angle of 154 deg. This is believed to be the most hydrophobic and lowest surface tension crystalline substance known. Analysis of the x-ray crystal st...

Zusammenfassung:	Fluorinated Polyhedral Oligomeric Silsesquioxanes are hydrophobic nanoparticles. One compound, FD8T8, is ultrahydrophobic, possessing a water contact angle of 154 deg. This is believed to be the most hydrophobic and lowest surface tension crystalline substance known. Analysis of the x-ray crystal structure indicates a large number of Si...F contacts may lead to ultrahydrophobicity. Prepared in collaboration with ERC Incorporated, Edwards Air Force Base, CA. Presented at the National Meeting & Exposition of the American Chemical Society (231st) held in Atlanta, GA on 26-30 Mar 2006; submitted for publication as an American Chemical Society (ACS) Symposium Series Book Chapter.
