Stability And Retention Enhancement Of Low Fouling Polystyrene Sulfonic Acid (Pss) And Polyethylene Glycol (Peg) Blend Films With Silane Coupling Agents, Sean Stybel
Williams Honors College, Honors Research Projects
The goal of this research project was to apply silane coupling agents for enhanced stability and retention of a low fouling polymeric coating to an inorganic substrate. A blend of polystyrene sulfonic acid (PSS) and polyethylene glycol (PEG) was crosslinked in order to create a low fouling film. The film was prepared by spin coating a PSS-PEG solution on an inorganic substrate coated with a layer of a silane coupling agent (3-aminopropyltriethoxysilane, APTES, solution), followed by thermal curing. The research was limited to less than one year and only used lab equipment available at the University of Akron. Stability and …
Characterization Of Polyurethane For Use As Substrate In Nanofiber Sensor For Biomedical Applications, Megan Theaker
Characterization Of Polyurethane For Use As Substrate In Nanofiber Sensor For Biomedical Applications, Megan Theaker
Williams Honors College, Honors Research Projects
The purpose of this project is to begin to determine properties of polymer nanocomposites that make a suitable substrate for nanofiber sensors. In this work, sensitivity of a sodium ion selective sensor constructed with polyurethane was used as a benchmark for comparison with sensors constructed with nylon-6. The sensors were characterized using contact angle and chronoamperometry. Using an ANOVA analysis, the results showed that the multi-walled carbon nanotube type was a significant factor on sensor response both with and without additional functionalization of the polymer by calixarene. The weight percentage of polyurethane in the electrospinning solution was also statistically significant …
Design Of Rubber Extraction Process From Tks Dandelion, Trevor A. Cody
Design Of Rubber Extraction Process From Tks Dandelion, Trevor A. Cody
Williams Honors College, Honors Research Projects
A design was developed for a controlled environment agriculture 3D greenhouse to grow and harvest TKS dandelions, as well as a processing plant to extract natural rubber and inulin from the roots. The design capacity was scaled for both pilot- and full-scale production: 100 and 100,000 tonnes of natural rubber per year, respectively. The byproducts of the process were dandelion greens, inulin, cellulose, and glucose; all of these except for cellulose were able to be valorized. The greenhouse was designed based on existing 3D hydroponic growing environments, and the extraction process was designed based on the original TKS dandelion extraction …
