文摘
- •
PVDF containing vinyl pendent groups was synthesized by a novel strategy.
- •
The PVDF-g-PAMPS copolymer was synthesized by grafting through RAFT polymerization.
- •
Nanoparticles as protonic conductor can provide a special pathway for proton transport.
- •
The high proton conductivity (20 mS/cm at room temperature) was observed for the new PEM.
- •
The power density as high as 34.3 mW/cm2 at peak current density of 140 mA/cm2 was observed for the new PEM.
