Potassium ion conducting nanocomposite polymer electrolytes was prepared by employing the solvent casting technique. Poly ethyl methacrylate (PEMA), potassium thiocyanate (KSCN) and nano-strontium titanate (SrTiO₃) (<100 nm) was used as a polymer host, an electrolyte and a filler, respectively. The complex formation between PEMA, KSCN and SrTiO₃ was confirmed through Fourier transform infrared (FTIR) and X-ray diffraction (XRD) analysis, respectively. This system exhibited two ionic conductivity maxima, but the sample, PEMA/KSCN/4 wt% SrTiO₃ delivered a maximum ionic conductivity of 3.07 × 10⁻⁵ Scm⁻¹ at room temperature, which was 10² times greater than that of PEMA/KSCN system. Truckhan model was employed to determine the diffusion coefficient, mobility and mobile ion concentration of the system. The remarkable change in surface morphology of the sample was observed through Scanning Electron Microscopy (SEM) micrograph.

采用溶剂浇铸技术制备了钾离子导电纳米复合聚合物电解质。聚甲基丙烯酸乙酯（PEMA）、硫氰酸钾（KSCN）和纳米钛酸锶（SrTiO ₃）（<100 nm）分别用作聚合物主体、电解质和填料。分别通过傅里叶变换红外 (FTIR) 和 X 射线衍射 (XRD) 分析证实了PEMA、KSCN 和 SrTiO ₃之间的复合物形成。该系统表现出两个离子电导率最大值，但样品 PEMA/KSCN/4 wt% SrTiO ₃在室温下提供了 3.07 × 10 ^-5 Scm ^-1的最大离子电导率，即 10 ²比 PEMA/KSCN 系统大几倍。Truckhan 模型用于确定系统的扩散系数、迁移率和移动离子浓度。通过扫描电子显微镜 (SEM) 显微照片观察到样品表面形态的显着变化。
