摘要

Fluorinated Polyhedral Oligomeric Silsesquioxanes are hydrophobic nanoparticles. One compound, FD_8T_8, is ultrahydrophobic, possessing a water contact angle of 154°. 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. Hydrophobicity of poly(chlorotrifluoroethylene) nanocomposites also increases with the incorporation of FluoroPOSS and will be discussed.
