Swelling Studies Of Poly(Ionic Liquids) In Different Solvents And Salt Solutions, Pierson Perdue, Ali Alshaikh, Creighton Baltier, Jason E. Bara, Sourav Chatterjee

Scholars Week

Poly(ionic liquid)s (PILs) represented a special class of polymers, which comprised of a polymeric backbone and ionic liquids (ILs) species in each monomeric repeating units. PILs has properties that combined the properties of ionic liquids (ILs) (i.e., high conductivity, better thermal and chemical stability, and tailor-made functionality) with the intrinsic properties of polymer (i.e., mechanical stability). This synergistic property makes PILs a good candidate for various applications such as stable-ion conductors, membranes for gas separations and sorbents. In the past, it was shown that PILs are capable of swelling when dissolved in different ILs but there are few literature reported …

Synthesis And Characterization Of Semi-Interpenetrating And Double Networks Of Sulfonimide- And Imidazolium-Containing Poly(Ionic Liquids), Jeremiah Coughlon, Seth Taylor, Jason Bara, Kevin Miller, Sourav Chatterjee

Scholars Week

In recent years, there has been increased research interest in creating electrically conductive polymer membranes with materials that are widely available and environmentally safe. Herein, we report how polymeric membranes comprised of unique combinations of ionenes and poly(ionic liquids), including a recently developed sulfonimide- and imidazolium-containing methacryloxy-based monomer, were produced via UV photopolymerization. These membranes were specifically tailored to exhibit both ionic conductivity and an affinity for carbon dioxide, which are both crucial characteristics in such applications as electron transport in lithium-ion batteries and gas sorbency in separation techniques. Monomers, such as the aforementioned methacryloxy-based ionic liquid (IL) and C4VIm, …

Soil Properties Associated with Land Management Practices in Western Kentucky

1. A. Isaacs, G. Moffitt, W. Sides, and Corey Hale

Mentor: Dr. I.P. Handayani

Hutson School of Agriculture, Murray State University, Kentucky, USA

Abstract

One of the most important factors regarding soil and plant health is nutrient availability and fertility. Of these two factors that were mentioned available potassium is a key component. With that being said we decided that it would be beneficial to see how potassium can be traced within the soil in various locations after fertilizer is applied. There were two parts to this experiment. Part one was …

Physiochemical Properties Of Urethane-Containing Ionic Liquids And Ionenes From A Non-Isocyanate Synthetic Approach, George Timmermann

Scholars Week

Ionic polymers that are designed to contain ionic liquids (ILs) in their backbones have been shown to exhibit a high degree of variability through changing the type of ionic character and the location of the ionic region within the molecule. This large amount of variability in both the structure and characteristics of ILs allows researchers to design task-specific ionic polymers and ILs for a variety of applications including gas separation membranes and solid polymer electrolytes. The synthesis of a specific class of ILs and ionenes through the incorporation of urethane groups with imidazolium rings by reacting carbonyl diimidazole with various …
