Übersicht

Trimethoxy(octyl)silan (TMOS) ist ein Organosilan, das als Kopplungs- und Oberflächenmodifizierungsmittel verwendet wird, um den Wasserkontaktwinkel zu vergrößern und die Oberflächenenergie zu verringern

Trimethoxy(octyl)silan wurde für die Silanisierung von Siliziumdioxid-Nanopartikeln verwendet, und es wurde über die Oberflächenmodifizierung von hydrophoben (T805) Titandioxid-Partikeln mit dem Silan berichtet.

rimethoxy(octyl)silan (TMOS) wird verwendet, um die Oberfläche von Siliziumdioxid zu funktionalisieren, um die Adhäsion mit Goldnanopartikeln (AuNPs) für die Verwendung bei der Herstellung von photonischen Geräten auf Acrylat-Nanokompositbasis zu fördern. Es kann auf Epoxidfasern auf Basis von Siliziumdioxid aufgetragen werden, um die hydrophoben Eigenschaften zu verbessern und die Oberfläche vor Korrosion zu schützen.
