Charakterisierung von Adsorptionsschichten linearer Polyester und Polyäther und ihrer gegenseitigen Wechselwirkung an der Oberfläche von wasserfreiem, pyrogenem TiO2(Anatas)

Abstract: ZUSAMMENFASSUNG:Die Adsorptionsschichten mehrerer linearer Polyester und Pojyather an der porenlosen Oberflache von wasserfreiem, pyrogenem Ti02 (Anatas) werden durch IR-spektroskopische Haftstellenzahl-und Adsorptionsmengenbestimmungen charakterisiert. Zur vollstiindigen Wasserdesorption ist eine thermische Vorbehandlung notwendig, die eine sehr aktive Oberflache hinterlaDt. An ihr liegen kaum OH-Gruppen, sondern fast ausschlieDlich Titanionen mit unvollstandiger O'--Koordinationssphare als Lewis-Adsorptionsz… Show more

“…The general differences in shape of the two sets of isotherms are typical for polymer compared to oligomer adsorption and consistent with previous findings. 22 Polymers are more readily adsorbed from solutions of extremely low concentrations onto solid surfaces due to their capability of multiple contact-making. Low molecular According to infrared investigations of poly(oxyethylene) adsorption from solution in CC14 onto silica the specific interaction proceeds via hydrogen bond formation from surface hydroxyl groups as donors to ether oxygen atoms as acceptors.…”
