Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

Advanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

The removal of thermally aged films of triacylglycerides by surfactant solutions [PDF]

, 2013
Thermal ageing of triacylglycerides (TAG) at high temperatures produces films which resist removal using aqueous surfactant solutions. We used a mass loss method to investigate the removal of thermally aged TAG films from hard surfaces using aqueous ...

Evaluation of Electrolyte Additives for High‐Temperature Polymer Electrolyte Fuel Cells

ChemElectroChem, 2016
AbstractIn this study, perfluoroalkyl phosphonic acids CF3PO3H2 and C2F5PO3H2 are investigated as additives to phosphoric acid to improve the oxygen reduction reaction (ORR) of high‐temperature polymer electrolyte (PEM) fuel cells. A comprehensive characterization of acid mixtures composed of 20 wt % additive and 80 wt % concentrated phosphoric acid is

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries
