摘要

本文研究了以碳纳米管为填料,改善低温燃料电池用聚偏氟乙烯(PVdF)基聚合物电解质的离子输运性能。采用XRD、光学显微镜、阻抗谱和介电弛豫测量等实验手段研究了填料对电解质结构和电学行为的影响。采用碳纳米管填充颗粒分散的聚偏氟乙烯基聚合物电解质的非晶态性质和离子电导率均有改善。电介质图显示了弛豫时间的色散性质和跳变机制是纳米复合聚合物电解质离子导电的主要原因。

Synthesis and characterisation of PVdF-{(NH4)2[C4H8 (COO)2]}: CNT gel electrolyte for Lt fuel cell application
In the present work, improvement of ion transport property in poly (vinylidene) fluoride (PVdF) - based polymer electrolytes for the use of low temperature fuel cell application have been investigated using CNT as fillers. The effect of filler, on structural and electrical behavior of electrolyte were studied by different experimental tools namely, XRD, Optical microscopy, impedance spectroscopy, and dielectric relaxation measurement. Improvement in amorphous nature and ionic conductivity has been observed for PVdF based polymer electrolytes dispersed with CNT filler particle. Dielectric plots show dispersive nature of relaxation time and hopping mechanism appears to be responsible for ionic conduction of the nanocomposite polymer electrolyte.
