Abstract

This research project utilizes solution and solid state Nuclear Magnetic Resonance (NMR) spectroscopy, along with Fourier Transform Infrared Spectroscopy (FT-IR) to examine the mechanism by which silanes attach to alumina nanoporous membranes under given reaction conditions. Octadecyltrimethoxysilane (ODTMS) is used due to previous research in its alteration of transport across these alumina nanoporous membranes. Solution NMR using 29Si, 13C indicates the lack of expected reaction byproducts by covalent attachments. However, SSNMR and FT-IR appear to show the presence of the silane after reaction; but, 1H SSNMR also seems to indicate unchanged peak integration ratios between the ODTMS methoxy and methylene protons.
