Abstract: Unique polymers and copolymers generated via oMLD processes are described alongside the methods for tuning such polymer and copolymer structures and redox chemistries. The polymers and copolymers described can incorporate monomeric species previously held to have too high an oxidation potential for successful use in oMLD, can exhibit unexpected redox chemistry from the adjustable incorporation of primary amine monomers and resulting azo functional groups, and show superior performance metrics when compared to polymers and copolymers synthesized by other methods. Applications for these polymers and copolymers are also described.

Abstract: A method of depositing a nanoscale-thin film onto a substrate is disclosed. The method generally comprises depositing a layer of a solid or gaseous state functionalizing molecule onto or adjacent to the first surface of the substrate and exposing the first surface to a source of ionizing radiation, thereby functionalizing the first surface of the substrate. Once the layer of functionalizing molecule is removed, a nanoscale-thin film is then deposited onto the functionalized first surface of the substrate.

Abstract: Disclosed are the electrochemical effects of crosslinking polymer chains in nanoscale polypyrrole films with aliphatic ethyl (Ppy-Et), propyl (Ppy-Pr), and butyl (Ppy-Bu) groups were investigated. The films are synthesized by pulsed-electrodeposition of polypyrrole followed by a crosslinking reaction with an alkyl dihalide (dibromoethane, dibromobutane, or dibromopropane) in methanol. By changing the length of the alkyl-dihalide crosslinker, it was shown that one can adjust the properties of the polypyrrole films to achieve properties not typical for polypyrrole. The resulting materials exhibit valuable properties in two areas: (1) excluding anions from transport through the polymer, allowing for the creation of cation-selective membranes using polpyrrole crosslinked with ethyl (2 carbon) crosslinker molecules and (2) enhancing the specific capacity by >50% relative to the uncrosslinked polymer using propyl (3 carbon) crosslinker molecules. These materials have potential value for energy storage, electrochemical desalination, membrane separations, and chemical sensors.
