Using a colloidal suspension, electrochemically active tungsten oxide thin films (150 nm) have been prepared via ultrasonic spray deposition using two different current collectors, namely TiN and Pt.
Self-assembled
monolayers of corrosion inhibitors of the mercaptobenzimidazole
family, SH-BimH, SH-BimH-5NH2, and SH-BimH-5OMe, were formed
on template-stripped ultraflat Au surfaces using microcontact printing,
and subsequently analyzed using X-ray photoelectron spectroscopy (XPS),
atomic force microscopy (AFM), and AFM-force spectroscopy (AFM-FS)
using a quantitative imaging (QI) mode. Printing of all used inhibitor
molecules resulted in clear patterns and in slightly more compact
films compared to immersion. The stability of the monolayers is further
probed by AFM-FS. Adhesion values of laterally heterogeneous inhibitor-modified
surfaces compared to bare Au surfaces, nonpatterned areas, and fully
covered surfaces are analyzed and discussed. Microcontact printing
confers a superior nanomechanical stability to imidazole-modified
films of the printed surface patches as compared to homogeneously
covered surfaces by immersion into the inhibitor solution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
