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. …
