The Structure Of Y-Aminopropyltriethoxysilane On Glass Surfaces

The structure of y-aminopropyltriethoxysilane (APS) has been studied in aqueous solution and as a solid using Fourier transform infrared spectroscopy. The monomeric aminosilane forms an internal cyclic chelate structure when hydrolyzed. Two vibrational bands have been found near 1575 and 1600 cm-1 in condensed aminopropylsiloxane polymer. The band at 1575cm-1 is assigned to the NH2 deformation mode of the acceptor amine groups involved in strong hydrogen bonding and the band at 1600 cm-1 is assigned to the NH2 groups. Heat treatment causes the formation of nonring chain-structured aminosilanes.
