Abstract
This research presents the influence of lithium bromide (LiBr) on the electrical properties of alginate in bio-based polymer electrolytes (BBPEs) system. Bio-based alginate was prepared using the solution casting technique with various LiBr compositions. The ionic conductivity and electrical properties of the prepared BBPEs samples were studied using electrical impedance spectroscopy over a frequency range of 50 Hz–1 MHz. A maximum ionic conductivity of 7.46 × 10 −5 S cm 1 was obtained for a sample containing 15 wt. % lithium bromide-doped alginate BBPEs at ambient temperature (303 K). The electrical analysis revealed that the most conductive sample based on alginate-LiBr BBPEs has optimum dielectric constant and loss, which significantly increases as temperature increases. The dielectric properties show that all alginateLiBr BBPEs are in non-Debye behavior conditions, where no single relaxation occurs in the present system.
研究了溴化锂(LiBr)对生物基聚合物电解质(BBPE)体系中藻酸盐电性能的影响。采用溶液浇铸技术,用不同的溴化锂组成制备了生物基海藻酸盐。使用电阻抗谱在50 Hz–1 MHz的频率范围内研究了所制备的BBPE样品的离子电导率和电学性质。在环境温度(303 K)下,含有15wt.%溴化锂掺杂的藻酸盐BBPE的样品的最大离子电导率为7.46×10−5 S cm 1。电学分析表明,基于藻酸盐-溴化锂BBPE的最具导电性的样品具有最佳的介电常数和损耗,其随着温度的升高而显著增加。介电性质表明,所有的藻酸盐LiBr-BBPE都处于非德拜行为条件下,在该条件下,本系统中没有发生单次弛豫。
