摘要
采用纳米Al2O3填充PVDF-HFP共聚物的方法,通过液-液萃取法制备了聚合物多孔膜。运用电化学方法测试了Al2O3含量对PVDF-HFP电解质膜的离子电导率、Li+离子迁移数、Li+离子输运活化能的影响。并通过分析填充纳米Al2O3的PVDF-HFP膜的FT-IR光谱图,从微观上说明了Al2O3与聚合物电解质膜中的PVDF-HFP基体存在相互作用。
Nanometeric Al2O3 particles used to fill in PVDF-HFP copolymer membrane were introduced in this paper. The micro-porous polymer membranes were fabricated by liquid-liquid extraction method. The ionic conductivity, ions transference number and activation energy for ions migration of the resulting polymer electrolyte were measured by electrochemical methods. It suggested an interaction between nanometeric Al2O3 particles and PVDF-HFP polymer matrix in polymer electrolyte membrane from the FT-IR spectroscopy.
