Hydrophobic Silsesquioxane Nanoparticles and Nanocomposite Surfaces

摘要

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-deg F contacts may lead to ultrahydrophobicity.
