Ion Exchange

Ion Exchange

Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or basic...

Types of Reversible Electrodes

Types of Reversible Electrodes

For electrode reversibility to be maintained, all the reactants and products involved in the half-reaction must be present at the electrode. There are several types of reversible electrodes (half-cells).In metal-metal-ion electrodes, a metal balances electrochemically with a solution of its own ions. Examples are Cu2+|Cu and Zn2+|Zn. Metals that react with the solvent, like group 1 and most group 2 metals, which react with water, and zinc, which reacts with aqueous acidic solutions, cannot be...

Electrochemical characterization of electrochromic switching in aqueous electrolytes.

Main Results:

Successfully synthesized water-soluble electrochromic polymers (WS-ECP-Blue-A and WS-ECP-Blue-R) processable from aqueous solutions.
Achieved significant electrochromic contrast (38-39% Δ%T) with rapid switching times (0.5 s) in aqueous electrolytes.
Demonstrated solvent resistance of the neutralized polymer acid films.

Conclusions:

The developed polymers are promising candidates for aqueous-processable and aqueous-switching electrochromic materials.
These materials offer a sustainable alternative for electrochromic devices, reducing environmental impact.
