Abstract

The development of solid polymer electrolytes based on natural gums represents a promising step toward sustainable energy solutions, driven by their abundance, cost-effectiveness, biodegradability, and nontoxic nature. This study primarily focused on the fabrication of a solid polymer electrolyte using almond gum (Amygdalus communis) doped with NH₄SCN salt using solution casting method and investigated its impact on ionic conductivity. An ionic conductivity of 1.123 × 10⁻⁴ Scm⁻¹ was attained for the membrane with 40 wt% ammonium thiocyanate. Through XRD and FTIR analysis, the amorphous nature and the interaction of certain functional groups with the salt provided insights into its potential for use in sustainable energy systems. Transference number analysis confirmed the major charge carriers present in the polymer electrolyte.

掺nh4scn杏仁胶生物聚合物电解质的结构和电化学性能

基于天然树胶的固体聚合物电解质的开发代表了朝着可持续能源解决方案迈出的有希望的一步，因为它们的丰富性、成本效益、可生物降解性和无毒性。本研究主要以杏仁胶（Amygdalus communis）掺杂NH4SCN盐为原料，采用溶液浇铸法制备固态聚合物电解质，并研究其对离子电导率的影响。当硫氰酸铵含量为40%时，膜的离子电导率为1.123 × 10−4 Scm−1。通过XRD和FTIR分析，无定形性质和某些官能团与盐的相互作用为其在可持续能源系统中的应用潜力提供了见解。转移数分析证实了聚合物电解质中存在的主要载流子。
