Product Name:Quaternized Poly(phenylene oxide) (QPPO)
English Name:Quaternized Poly(phenylene oxide) (QPPO)
CAS No.:3032406-08-6
Aliases:QPPO, Quaternized PPO
Physical Properties:Quaternized poly(phenylene oxide) is a functional polyphenylene oxide polymer containing quaternary ammonium groups. It typically appears as light yellow to brown powder or granules, soluble in polar solvents such as N-methylpyrrolidone, dimethyl sulfoxide, and N,N-dimethylformamide. It exhibits good thermal stability and mechanical strength, and forms membranes with excellent ion conductivity.
Uses:Quaternized poly(phenylene oxide) is mainly used as an anion exchange membrane material in electrochemical devices such as alkaline fuel cells, water electrolysis for hydrogen production, electrodialysis, and redox flow batteries. It effectively conducts hydroxide ions while maintaining chemical stability.
Technical Specifications:
Ion exchange capacity (IEC): 0.5–2.0 mmol/g, tunable upon request.
Water uptake (room temperature): 10%–30%.
Thermal decomposition temperature (Td): ≥250°C under nitrogen atmosphere.
Tensile strength: 20–50 MPa.
Anion conductivity (60°C, 95% RH): 10–50 mS/cm.
