Major Contributions

1. Successfully developed a novel self-assembled PVDF/Graphene piezoelectric membrane that achieved significant dye degradation efficiency: 80.2% for methylene blue, 85.6% for crystal violet, 73.8% for methyl orange, and 96.1% for rhodamine B within 2 hours.

2. Demonstrated that graphene addition induced PVDF crystalline phase transformation from α-phase to electroactive β-phase through self-assembly, increasing the electroactive phase ratio from 34.58% to 95.85%, which significantly enhanced the membrane's piezoelectric properties.

3. Established that the optimized membrane exhibits superior piezoelectric performance with the highest Vpp value of 4.26 V and d33 value of 13.31 pm/V, providing a green strategy for future applications in environmental remediation.
