This paper aimed to study the influence of zirconium phosphate (ZrP) nanoparticles on reducing the diameter of nanofibres during electrospinning. Addition of metal oxide such as zirconium phosphate decreases the diameter and smooths on the polyacrylonitrile (PAN) nanofibres as observed by the SEM techniques. Furthermore, this work investigated the effect of zirconium phosphate on the morphology and conductivity of modified PAN nanofibres under SEM, XRD and electrochemical cells. The PAN/zirconium phosphate nanofibres were obtained with the diameter ranges between 100 and 200 nm, which mean that the nanofibres morphology significantly changed with the addition of the zirconium phosphate nanoparticles. The conductivity of PAN and PAN-Nafion zirconium phosphate nanofibres was more improved when compared to that of the plain PAN nanofibres as observed under electrochemical measurements. The plain PAN nanofibres show the total degradation on thermal gravimetric analysis results when compared to the modified PAN with zirconium phosphate nanoparticles. The thermal properties and proton conductivity make the PAN/ZrP nanofibres as promising nanofillers for fuel cell electrolytes.

Nafion®-聚丙烯腈/磷酸锆纳米纤维共混物的结构形态和电导率

本文旨在研究磷酸锆（ZrP）纳米粒子对减少静电纺丝过程中纳米纤维直径的影响。如通过SEM技术所观察到的那样，添加金属氧化物（例如磷酸锆）可减小直径并在聚丙烯腈（PAN）纳米纤维上变光滑。此外，这项工作研究了磷酸锆对在SEM，XRD和电化学电池下改性PAN纳米纤维的形态和电导率的影响。获得了直径在100至200 nm之间的PAN /磷酸锆纳米纤维，这意味着纳米纤维的形貌随着磷酸锆纳米颗粒的添加而发生了显着变化。与在电化学测量下观察到的普通PAN纳米纤维的电导率相比，PAN和PAN-Nafion磷酸锆纳米纤维的电导率得到了更大的改善。与具有磷酸锆纳米颗粒的改性PAN相比，普通PAN纳米纤维在热重分析结果上显示出总降解。PAN / ZrP纳米纤维的热性能和质子传导性使其成为用于燃料电池电解质的有前途的纳米填料。
