Characterization Of Self-Assembled Carboxylate Monolayers And Multilayers At Copper And Silver , Earl Laird Smith

Retrospective Theses and Dissertations

A variety of chemically modified surfaces were constructed by the self-assembly method via chemisorption onto evaporated metal films. Monolayer films, self-assembled from solution, include n-alkanoic acids, CH[subscript]3(CH[subscript]2)[subscript] nCOOH, and n-perfluoroalkanoic acids, CF[subscript]3(CF[subscript]2)[subscript] nCOOH, on copper, and n-alkanethiolates, CH[subscript]3(CH[subscript]2)[subscript] nSH on copper. Monolayer films were obtained from the gas phase, a newly developed technique, for n-alkanoic acids on silver, and n-alkanethiolates on silver and gold. Multilayer films obtained by self-assembly from the gas phase include n-alkanoic acids at copper and silver and perfluoroacids ...
