ABSTRACT
THE EFFECTS OF COLOR CONCENTRATES ON THE RHEOLOGY OF TINT BASES
Douglas James Herrick
Waterborne coatings are formulated with a number of different ingredients; water, latex polymers, pigments, surfactants, dispersants, defoamers, biocides, coalescing aids, and rheology modifiers or thickeners. Rheology modifiers are necessary in order to improve the physical properties of the coating before, during, and after application to a substrate. There are two kinds of rheology modifiers used in waterborne coatings; associative thickeners and non-associative thickeners. Coatings formulated with associative thickeners are quite sensitive to coating variations; the slightest change in the formulation has profound effects on the …

Development Of A Quantitative High Throughput Method For The Early Detection Of Corrosion On Coated Aluminum, Jeffrey Clayton Foster
Master's Theses
Eight fluorescent indicators were evaluated for their ability to detect the corrosion of aluminum metal substrates. The fluorophore Rhodamine-salicylaldehyde (RSA) was selected as a candidate for further study based on its ability to bind and detect aluminum ions at low concentrations, its selectivity for aluminum ions, its long-term stability, its solubility in our solvent-based epoxy formulation, and its compatibility with our testing method.
A recent publication suggested that an alternative method of fluorescence activation was possible—an acid-promoted ring opening that occurred in the absence of metal ions. To prove the capability of RSA to bind aluminum ions, thorough 1H …

The Development Of Transparent, Processable, Thermally-Responsive Coatings, Christopher David Roland
Master's Theses
Polymer matrices are commonly used as guest-host systems for organic chromophores for use in non-linear optical materials. The chromophores must be aligned or poled in an electric field in order to impart anisotropy and non-linear activity to the material. This poling process raises several issues, the two largest being the eventual relaxation of the chromophores back into random orientations due to brownian motion, and high molecular weight polymer matrices limiting chromophore mobility during poling. The prevention of this relaxation process is an area of significant interest, especially in applications that require long term coating stability and activity. In this study, …
The Synthesis Of A Homologous Series Of Alkyl Lumazines And Their Application To The Dispersion Of Carbon Nanotubes, William P. Kopcha
The Synthesis Of A Homologous Series Of Alkyl Lumazines And Their Application To The Dispersion Of Carbon Nanotubes, William P. Kopcha
Master's Theses
In this thesis, the synthesis of a series of alkyl lumazine surfactants (LCn) is reported. Their application to the dispersion of both CoMoCAT and HiPco single-walled carbon nanotubes (SWNTs) is examined in detail and the thermal stability and chirality selection properties of dispersions made with these surfactants were compared both between themselves and with an alkyl flavin surfactant (FC12). Lumazine alkyl chain length exhibited some control over the quality and the quantity of SWNTs dispersed. LC10 was deemed most appropriate for comparison with FC12 based on considerations of solubility and nanotube individualization. …
