摘要

以不同质量百分比的1-丁基-3-甲基咪唑双(三氟甲基磺酰基)亚胺(BMITFSI)为原料,采用溶液铸造法制备了甲基纤维素(MC) /壳聚糖与三酸铵(NH4TF)共混聚合物电解质。采用阻抗谱法对膜进行表征,测定其离子电导率。含有45% BMITFSI的样品在室温下的电导率最高,为(3.98±2.84)× 10-4 cm-1。采用复介电常数和复电模量对电导率最高的样品进行了介电数据分析。介电数据证明,电导率的提高主要是由于载流子数量的增加。

Effect of BMITFSI to the electrical properties of methycelloluse/chitosan/NH4TF-based polymer electrolyte
Blended polymer electrolyte of methylcellulose (MC) / chitosan with ammonium triflate (NH4TF) were prepared with different weight percentage of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMITFSI) via solution casting technique. The film was characterized by impedance spectroscopy to measure its ionic conductivity. Samples with 45% of BMITFSI exhibit the highest conductivity of (3.98 ± 2.84) x 10-4 Scm-1 at ambient. Dielectric data were analyzed by using complex permittivity and complex electrical modulus for the sample with highest conductivity. Dielectric data proves that the increase in conductivity is mainly due to the increase in number of charge carriers.
