Characterization of mixed monolayers with x-ray photoelectron spectroscopy (XPS)


EMSL Project ID
20494

Abstract

We are interested in the covalent immobilization of polymer thin films by a photochemically initiated ligation process, with special emphasis on how the surface and interface properties influence the outcome of the immobilization. The goal of this proposal is to use XPS to study the density of the photocrosslinker on mixed-monolayer functionalized surfaces. Results from these studies will be correlated with our solution studies. A revised manuscript incorporating these results with EMSL scientist as co-author will be submitted.
