Description

General description

(3-Aminopropyl)triethoxysilane (APTES) is an aminosilane that is majorly utilized in the chemical modification of a variety of surfaces such as alumina and silica. It can act as an adhesion promoter between the polymer and the substrate material. It can also be used in the immobilization of surface molecules. The attachment of APTES molecules with the atoms present on the surface happens through chemisorption which results in the formation of a self-assembled monolayer (SAM) on the substrate.

Application

APTES can be used in a variety of applications such as an anti-corrosive coating, surface treatment for biological applications, and capping of surface atoms for diagnostic applications.
