POLY 619 |
| Fluorinated Polyhedral Oligomeric Silsesquioxanes (FluoroPOSS) have been produced to act as reinforcements as well as to provide surface property enhancements in fluoropolymers. These compounds have the highest molecular weights, highest densities, and lowest surface tensions of any POSS compounds yet produced. These compounds can also be ultrahydrophobic. Water contact angle measurements, in conjunction with x-ray crystallography techniques, have been utilized to observe a correlation between hydrophobicity and nano-scale, molecular surface roughness. The synthesis, structural characteristics, and surface properties of these POSS compounds will be discussed. |
