Abstract
Perfluoropolyether-based org.-inorg. hybrids were prepd. by sol-gel process and applied as functional coatings onto glass substrates. Contact angle anal. and X-ray photoemission spectroscopy were carried out in order to characterize the surface of the prepd. coatings. A strong hydrophobic and lipophobic character was obsd. for all tested compns. The wettability behavior was found to be dependent on both the coating technique and the reaction time of the sol-gel reaction. A strong surface segregation of perfluoropolyether segments was noted for all the prepd. samples as evidenced by XPS anal. On the basis of the obtained results, these materials could be used as functional coatings to prep. water and oil repellent glasses or other substrates.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
