Uv Polymerization Of A Zwitterionic Antifouling Membrane Coating, Amanda Jia-Hwa Tsai, Vincent Matthew Guarino
Materials Engineering
Membrane filtration is used in a wide array of industries to separate components in a mixture. Filtration membranes suffer from the external deposition of pollutants and microorganisms, a phenomenon known as fouling. Fouling reduces the lifetime of a membrane and therefore increases production costs. The goal of this project was to modify the surface of a hydrophobic commercial membrane with a charged coating to induce antifouling properties. A zwitterionic monomer, sulfobetaine methacrylate (SBMA), was used for its steric hindrance and hydration shell formation mechanisms, which result in superior non-specific antifouling performance. When polymerizing the coating onto the surface of the …

Materials Engineering
The viability of renewable biopolymers as sustainable alternatives to synthetic plastics is promising, however ultra-violet (UV) radiation can lead to premature degradation and reduction in the material’s performance. Biopolymers comprised of nopal cactus juice, animal protein, natural wax, and glycerin in differing percentages were studied to obtain thermo-mechanical data in relation to UV exposure. To quantify degradation, dynamic mechanical analysis, thermogravimetric analysis, differential scanning calorimetry, infrared spectroscopy, goniometry and gravimetric measurements were performed. Each formulation experienced mass loss as a result of UV exposure, which could be attributed to water evaporation. The thermogravimetric analysis indicated a reduction in the second …

Nano-Enhanced Composite Membranes For Water Desalination, Benjamin Fredrik Victor Sundling Von Fürstenrecht
Materials Engineering
In theory single walled carbon nanotubes (SWCNT) will aid in ion rejection due hydrophobicity and smoothness of the SWCNT. An efficient means of water desalination utilizing SWCNT in a membrane seems plausible. A lyotropic liquid crystal (LLC) solution was made with a synthesized polymerizable surfactant methacryloxy ethyl hexadecyl dimethyl ammonium bromide (C16MA) to help with vertical alignment of SWCNT. Due to SWCNT lack of solubility and tendency to agglomerate in water, a dispersion performed using an inert surfactant centrimonium bromide (CTAB) to make sure that the SWCNT were homogeneously dispersed in the solution without altering the hexagonal packing factor of …

Minimizing The Dimensional Change In Two Component Epoxy Based Thermoset Adhesives Through Adapting Mix Ratio And Initial Crosslink Density, Jefferson Peter Norman
Materials Engineering
Meissner Filtration uses amine-hardened epoxy as a high-performance adhesive to encapsulate hollow fiber membranes at the ends of rigid filter housings. Dimensional change of the epoxy while curing can result in residual stress formation that is detrimental to the manufacturing of the filter and causes structural integrity issues when the filter is used in industrial processes where heating and cooling cycles are implemented. The residual stresses can cause cracks, microscopic fractures, and delamination from the housing, resulting in failure of the filter. The goal of this project was to evaluate how changes in processing conditions could minimize dimensional variability due …
