Swift heavy ion (SHI) irradiated PVDF and (0.8)PVDF/(0.2)BaTiO₃ films (thickness ~ 0.06 μm) have been studied as a separator for supercapacitors. Samples were irradiated by O⁶⁺ and Li³⁺ ions at fluence 2 × 10¹¹ and 2 × 10¹² ions/cm², respectively. The irradiation-induced α → β phase transition in the PVDF polymer matrix, whereas complete amorphization in BaTiO₃ filler is observed in nanocomposite films. The estimated value of percentage porosity (P%) for the irradiated composite films is comparable to the P% values for commercially available Cellulose separators. The flexibility is retained even after irradiation owing to irradiation-induced cross-linking in the PVDF matrix. The Cyclic Voltammetry (CV) curves retain their shape without distortion with increasing scan rate (20–180 mA s⁻¹) showing the high rate performance of the separators. The electrochemical impedance spectra of Ni/separator/Ni blocking cells after the 1st and 200th cycles are analyzed to evaluate the bulk electrolyte resistance (R_be) and conductivity under the cyclable performance of the separator films. The R_be for the 1st cycle for irradiated PVDF and (0.8)PVDF/(0.2)BaTiO₃ separator films are ranged from 0.4–1.4 Ω, which is much lower than R_be for commercially available non-porous Celgard™ 2500 (88.2 Ω) and micro-porous Celgard Ez 2090 (47.1 Ω) separators. However, the conductivity values are higher than that of commercially available Cellulose and Celgard™ 2500 separators.

研究了快速重离子（SHI）辐照的PVDF和（0.8）PVDF /（0.2）BaTiO ₃薄膜（厚度〜0.06μm）作为超级电容器的隔膜。样品分别以2×10 ¹¹和2×10 ¹²离子/ cm ^2的通量分别被O ⁶⁺和Li ³⁺离子照射。辐射诱导的PVDF聚合物基体中的α→β相变，而BaTiO _3中的完全非晶化在纳米复合膜中观察到填料。辐照的复合膜的孔隙率百分数（P％）的估计值与市售纤维素隔膜的P％值相当。由于在PVDF基体中由辐射引起的交联，即使在辐射后也保持了柔韧性。循环伏安法（CV）曲线随着扫描速率（20–180 mA s ^-1）的增加而保持其形状而不会变形，显示了分离器的高倍率性能。分析第1次和第200次循环后Ni /隔板/ Ni阻挡电池的电化学阻抗谱，以评估隔板膜可循环性能下的整体电解质电阻（R _be）和电导率。将R _BE对于第一周期的辐照PVDF和（0.8）PVDF /（0.2）BaTiO ₃隔离膜，其范围为0.4-1.4Ω，远低于市售无孔Celgard™2500（88.2Ω）和微米级的R _be -Celgard Ez 2090（47.1Ω）多孔隔板。但是，电导率值高于市售的Cellulose和Celgard™2500隔板的电导率值。
