摘要

本研究係以N－甲基吡咯烷酮（NMP）溶解聚偏二氟乙烯（PVDF）製備靜電紡絲液，並透過加入氧化石墨烯（GO）進行混摻，探討官能基、表面型態、接觸角、電阻度及電性能並評判應用於電池中的離子交換效果，研究顯示，與未加入氧化石墨烯（GO）之薄膜相比，電阻率提升25.9%、電壓提升0.12V、安培指數提升3.42%、功率提升1.14%，表示聚偏二氟乙烯（PVDF）紡絲液加入氧化石墨烯GO後可有效提高電池效率。

In this study, N-methylpyrrolidone (NMP) was used to dissolve polyvinylidene fluoride (PVDF) to prepare an electrospinning solution, and graphene oxide (GO) was added for mixing to discuss functional groups, surface morphology, and contact angles, Resistivity and electrical performance, and evaluate the ion exchange effect applied to the battery. The research shows that compared with the film without graphene oxide (GO), the research has achieved a resistivity rise to 1.62%, a voltage rise to 0.12V, ampere The index rose to 3.42% and the power rose to 1.14%, indicating that the addition of polyvinylidene fluoride (PVDF) spinning solution to graphene oxide GO can effectively improve battery efficiency.
