Poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) doped with zinc acetate polymer electrolytes have been prepared for electrochemical devices. Electrical conductivity (σ) obtained from impedance analysis shows a maximum (σ = 4.83 × 10–4 S cm−1) for 25 wt% of salt concentration, while Fourier transform infrared spectroscopy confirms the formation of composite electrolyte and information on the interaction of polymer matrix with the salt. Polarized optical microscopy shows the reduction in the crystallinity of polymer host due to salt doping which is also evidenced in the X-ray diffraction analysis of the samples. A sandwiched structure laboratory-scale supercapacitor has been fabricated using the highest conductivity polymer electrolyte film and activated graphene oxide electrode shows promising results.

用于超级电容器应用的聚（偏二氟乙烯-共-六氟丙烯）掺杂醋酸锌聚合物电解质

掺杂有醋酸锌聚合物电解质的聚（偏二氟乙烯-共六氟丙烯）（PVdF-HFP）已被制备用于电化学装置。从阻抗分析获得的电导率 (σ) 在 25 wt% 的盐浓度下显示出最大值 (σ = 4.83 × 10–4 S cm−1)，而傅里叶变换红外光谱证实了复合电解质的形成和有关相互作用的信息聚合物基质与盐。偏振光学显微镜显示由于盐掺杂导致聚合物主体的结晶度降低，这也在样品的 X 射线衍射分析中得到证实。使用导电率最高的聚合物电解质膜和活化的氧化石墨烯电极制造了一种夹层结构的实验室规模超级电容器，显示出令人鼓舞的结果。
