Silane Interphase of Composites: Effects of Process Conditions on Gamma-Aminopropyltriethoxysilane

摘要

FT-IR spectroscopy was used to collect spectra of gamma-aminopropyltriethoxy silane (gamma-APS) coupling agent deposited on KBr plates, modelling the silane interphase of composites, to study the effects of heating the gamma-APS film under various environmental conditions. This coupling agent is used in fiber reinforced epoxy composites. An aminebicarbonate salt forms when the sample is dried in a moist carbon dioxide environment giving rise to a series of bands.
