Polymer blend electrolytes based on chitosan: methylcellulose loaded with ammonium nitrate (NH4NO3) were fabricated by solution cast method and characterized by XRD, FTIR, EIS, FESEM, and TNM techniques. XRD is used to show the decrease of the crystalline structure. FTIR method is used to confirm the interaction between electrolyte elements. The maximum room temperature DC conductivity of 3.54נ10−4 S cm−1 is provided by the highest conducting system using EIS data. The FESEM method showed that the morphology of the film has a uniform smooth surface at the highest salt concentration. This is in good agreement with the XRD, FTIR, and EIS results. The dielectric constant is high at the low frequency region due to electrode polarization. Transference number measurement (TNM) is used to show the dominant charge carriers. The values of the transference number of electron (telectron) and ion (tion) showed that the ions are dominant. The TNM measurement shows the compatibility of the system for electrochemical energy storage device application.

掺杂不同浓度 NH4NO3 的壳聚糖/甲基纤维素共混聚合物的结构、形态和电学性质

基于壳聚糖:甲基纤维素负载硝酸铵(NH 4 NO 3)的聚合物共混电解质通过溶液浇铸法制备,并通过XRD、FTIR、EIS、FESEM和TNM技术进行表征。XRD用于显示晶体结构的减少。FTIR 方法用于确认电解质元素之间的相互作用。最高室温直流电导率为 3.54נ10 -4 S cm -1由使用 EIS 数据的最高传导系统提供。FESEM 方法表明,在最高盐浓度下,薄膜的形貌具有均匀光滑的表面。这与 XRD、FTIR 和 EIS 结果非常一致。由于电极极化,低频区域的介电常数很高。转移数测量 (TNM) 用于显示主要电荷载流子。电子(t electron )和离子(t ion )的转移数的值表明离子占优势。TNM 测量显示了系统在电化学储能设备应用中的兼容性。
