The research progress in polyethylene oxide polymer electrolytes

FlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Atmospheric Corrosion Protection of LPBF Manufactured AlSi10Mg by Combining SiOx‐CVD and PDMS Grafting

Materials and Corrosion, EarlyView.
Hybrid SiOₓ‐CVD/PDMS ultrathin films mitigate atmospheric corrosion of additively manufactured AlSi10Mg. Electrochemical analyses show reduced corrosion currents, increased charge‐transfer resistance, and suppressed pitting due to diminished cathodic activity and limited oxygen and ion transport under NaCl exposure.

Corrosion Inhibition of S275 Carbon Steel in CO2 Capture Systems Using Monoethanolamine (MEA) Solvent

Materials and Corrosion, EarlyView.
Corrosion inhibitors CuSO4 and NaVO3 achieved up to 98% inhibition efficiency for carbon steel S275 in CO2‐loaded MEA solvent, reducing corrosion rates to 9.4 µm/year—outperforming costly stainless steel SS 316 L at a fraction of the cost. ABSTRACT Corrosion in CO2 capture units significantly impacts safety and costs.
