Addition of doping materials can possibly enhance the ionic conduction of solid polymer electrolyte (SPE). In this work, a new SPE using 2-hydroxyethyl cellulose (2-HEC) incorporated with different ammonium nitrate (NHNO) composition was prepared via solution casting method. Studies of structural properties were conducted to correlate the ionic conductivity of 2-HECNHNO SPE using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. Encouraging result was obtained as the ionic conductivity increased about two orders of magnitude upon addition of 12wt% of NHNO. XRD analysis shows the most amorphous SPE was obtained at 12-NHNO. From FTIR spectra, the interactions between 2-HEC and NHNO were observed by the shifts of COH peak from 1355cm to 1330cm and the presence of new NH peak in the OH region. The spectrum has been validated theoretically using Gaussian software. The results obtained from this study corroborate that the complexes of 2-HEC and NHNO responsible to promote the ionic conductivity to the higher value.
添加掺杂材料可能会增强固体聚合物电解质（SPE）的离子导电性。在这项工作中，通过溶液浇铸法制备了一种使用 2-羟乙基纤维素（2-HEC）与不同硝酸铵（NHNO）组成的新型 SPE。使用 X 射线衍射（XRD）和傅里叶变换红外（FTIR）光谱对结构性能进行了研究，以关联 2-HEC-NHNO SPE 的离子电导率。令人鼓舞的结果是，在添加 12wt%的 NHNO 时，离子电导率增加了约两个数量级。XRD 分析表明，在 12-NHNO 时获得了最非晶态 SPE。从 FTIR 光谱可以看出，通过 COH 峰从 1355cm 向 1330cm 的位移以及 OH 区域中 NH 峰的出现，观察到 2-HEC 和 NHNO 之间的相互作用。使用 Gaussian 软件对光谱进行了理论验证。该研究的结果证实，2-HEC 和 NHNO 的复合物负责将离子电导率提高到更高的值。
