摘要:
Nanoreinforced coatings with improved hydrophobicity, thermal stability, hardness, and durability have been developed from polyhedral oligomeric silsesquioxane (POSS) reagents and resins. The nanoscopic dimensions and hybrid (organic/inorganic) composition of POSS reagents are particularly useful for coating fillers derived from minerals, metals, glasses, and polymeric materials.
摘要:
A synthetic process for polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) produces silanol and siloxide molecules containing both olefinic groups and alkyl or aromatic groups. Olefin-bearing POSS silanol/siloxides are derivatized into a variety of chemical species while retaining the ability to further derivatize the silanol/siloxide.
