Discharge Efficiency

Most researchers proved that adding PMMA in PVDF can reduce the crystal size of β-phase and improve the discharge efficiency. However, we found that PMMA could facilitate the formation of a new crystal variety (γ-2b), which contributes more to the improvement of discharge efficiency.
